A Complete Guide to Using Slugs as a Resource with Indian Runner Ducks

This article is for all those people out there who are under regular attack from the cursed slug. If you live in Great Britain or North Wales like I do, you know all to well about these little beasts. 2012 was a year of slug plagues for most gardeners in the UK due to the wet and humid weather which provided ideal breeding conditions. And with climate change these wet, humid summers are not likely to go away, so it’s best to get prepared.

Slug plagues are of course a symptom of an unbalanced ecosystem in that their natural predators and parasites are not abundant enough to balance the slug population. A balanced ecosystem takes time to establish so slugs can be a big problem in newly created permaculture gardens, especially when mulch is used. I would like to tell you about the fastest most entertaining and resourceful way of getting rid of your slugs.

After trying the traditional methods of using beer and orange peel traps, but still finding severed pumpkins and courgettes, I took to going out in the dead of night with a torch in the rain hunting down the little blighters and collecting them after catching them in the act of munching on virtually everything — including herbs that where planted to deter them. I caught hundreds using this method but what to do with them once I had caught them was the problem and I couldn’t keep going out every night hunting slugs.

After the news of my slimy blight got around, a box of blue Indian Runner Duck eggs appeared on my kitchen table. I had been assured by a friend that Indian Runners love slugs and don’t make a mess of the garden. I was doubtful because years previously, after hearing Bill Mollison’s advice that “no one has a slug problem, they have a duck deficiency”, I got myself some Pekin Ducks that refused to eat any slugs and just ate my courgettes instead. After that, I gave up hope on ducks. Admittedly, the breed Bill recommended was a Khaki Campbell. I didn’t take this advice because I had a friend that kept his Khaki Campbells fenced in because they ate his crops as well as the slugs.

I no longer have a slug problem, just two very fat ducks that come running when on the odd occasion I find a very unlucky slug. Slugs are their favourite food and so I have gone from having thousands of slugs to virtually none. This transformation happened within just a few days. They will eat as many slugs as you can throw at them and the beauty of it is that they convert slugs to eggs, which feed me, and guano which feeds the garden.

So, now my slugs are a resource.

Indian runners are the ducks for the job. They don’t like swimming, so they won’t ruin your pond and they don’t eat your greens either — but they do like to eat green caterpillars. You can leave them free to roam and they make a very entertaining garden companion as they follow me around begging for slugs and eating any insects that I happen to unveil. However, my ducks were trained in being super-effective pest munchers, so I don’t know how they would fare if just left to their own devices, without any training. For your help I have included a section on training your Indian Runners to be excellent slug guzzlers.

How many ducks do you need?

I have two ducks roaming over a 3rd of an acre veggie garden as well as a huge courtyard. With this number I trust them completely to free range. I am planning on getting two more females, which I believe will do more good than harm. It is easier to train them and keep them under control the fewer ducks you have, although you could have a temporary pen to keep them under control when needs be.

Obtaining Indian Runners

You can buy Indian Runner eggs very simply online, from sites such as E-bay, and they can be delivered to your door. Make sure you get a reputable egg supplier to ensure your ducks will be healthy and you will have a high egg hatching rate. You may also be able to obtain them from a farmers’ market or poultry rearer in your area. If you choose to get a mallard, then only have one to as many females as possible as they can cause considerable stress to females.

Incubating

Normally your local farmer will know who to borrow an incubator from. You can easily ply him with cake to make him more obliging. This will also be useful in the future when you need his straw. Ensure the incubator is spotlessly clean using 1 in 5 dettol mix then thoroughly rinse afterwards. It is very important that your eggs remain pathogen free as they are very vulnerable to infection.

Always handle your eggs with clean hands. Discard any that have breaks or fractures as they could pass disease on to the other eggs.

Keep the eggs cool at around 18.33 degrees Celsius until you are ready to incubate them. Before you put your eggs in the incubator run it for day or two to ensure the temperature stays at precisely 37.5 degrees Celsius. Place a bowl of water in the incubator to keep the environment humid — this is essential for ducklings. Rotate the eggs at least once a day laying them on their sides and rotating them 160 degrees. This ensures the ducklings don’t stick to the side of the shell. Open the incubator as little as possible during incubation to ensure the desired temperature and humidity is maintained.

Within two days you will be able to see which eggs are fertilised. You can do this by holding a powerful torch to them — you should see a shadow inside. This is the development of the blastodisc. Discard any unfertilised eggs as these could spread infection to the others. You can watch the development of the eggs using the torch but be warned, only do this when you are turning to avoid loss of humidity and temperature in the incubator.

Hatching

After 25-28 days you should start to hear cheeping and may see the first crack appearing. Increase the humidity by adding another bowl of water so that there is actually condensation in the incubator. The eggs need to be really moist if they are to hatch. They can take up to 24 hours to hatch so be patient. You can help them by placing a wet tea towel around them which will help them to break free of the shell.
If the chicks take longer than 24 hours after first beginning to break free of the shell then you can help by using a pair of tweezers to pull back tiny fragments of shell with the aim of revealing the beak. Only take off tiny fragments and do not proceed if the fragment has red veins on it, as doing so will kill the chick at this stage.

Once the beak is free you can help the chick by gently feeding it sugary water on a spoon. This will give it more energy for the rest of its breakout. Some duck breeders will say if it can’t hatch itself then it won’t survive anyway and that you should never intervene. However I had to intervene with my chicks and they are now healthy and strong ducks and I have met people who have done the same with success. As long as you follow the precautions and provide suitable after care I believe that it is safe.

After-care of chicks

After they are born, put them in a dry box with newspaper and keep them warm at around 37.5 degrees Celsius. If you don’t have a heat lamp or suitable heater then a normal lamp will do. Mount it over the box so the chicks can go under it at will or move away if they are too warm. Ensure that the lamp does not overheat the box and start a fire. Put a shallow bowl of water in with the chicks in the opposite corner to the heat source. You will need to show them how to drink — do this by gently lifting the bowl to their beaks or use a spoon to encourage them to drink. They soon learn.

Remember captive-bred ducks such as Indian Runners lack many of the natural instincts. They will be hungry, so feed them chick mash mixed with water. You can get this online or from pet stores. Keep the box clean and dry. After one week you will be amazed at how much they have grown. You can now take away the heat lamp as long as the temperature remains at around 20 degrees Celsius.

Housing

The ducks are very hardy once they have their adult feathers. And will happily live in any shelter that is dry and fox-proof — providing that they can get into it, as they are not great climbers and will just fall straight off a ramp. But, they can handle steps.

If you want the ducks to lay in the same place as they sleep, ensure that it is dark and sheltered and provide bedding. The cheapest and most reliable way of getting cheap bedding is by calling up your local tree surgeon and ask them for their wood chips. They will give you this free of charge as they usually have to pay to dispose of it. The beauty of wood chips is that you layer it and it starts to break down in the hutch and may even provide additional warmth depending on the size of the hutch. I also found a thriving worm population living in the wood chips, which provided a tasty treat for the ducks when I was cleaning their hutch out. Wood chips are great added to a compost pile and used as mulch around trees.

Here are some examples of the shelters that I created for them. I downsized after deciding I would actually need less birds.

How to train them

After two weeks take the ducklings out into the garden. They should follow you by now. Turn over rocks and look around ravaged plants for slugs and feed them directly to the ducks. If you whistle when you feed them or make a particular noise they will associate this with slug-time after a few days of repetition. Feed them lots of little slugs to start with and as they grow bigger, increase the size of the slugs. If you have snails, smash them with a rock first and then feed them to the ducks. The ducks will now follow you around the garden and you can feed them the various pests as you go.

How to get slugs where you want them

If you pile up rocks near your vegetables, or leave damp logs, the slugs will hide underneath. Orange peel is also a favoured hiding place. When you’re with the ducks, turn these hiding places over and feed the slugs too them. You can also point the slugs out to them and they will soon learn to pick them off themselves. Do the same with caterpillars — picking them off at first and feeding them to the ducks, and then showing the ducks where they are. After a while of feeding the ducks and whistling them you will be able to call them over to you when you find a slug in the garden and they will know what to look for when they come to you.

Feeding the ducks when there are no slugs left

I feed the ducks on a varied diet to ensure they get all the nutrients they need, although it seems they would only eat slugs if given the opportunity. They also get kitchen scraps such as rice, pastry, cake, porridge and pasta, but they do not like greens. I supplement this with worms from my worm farm. I feed the worms the rest of my kitchen scraps apart from orange peel and onions. And I also supplement them with organic layers pellets to ensure they have got everything they need in their diet.

  1. Thank you for such an enjoyable, visual & useful report to save & share, especially with friends in the US northwest! This is so much more interesting than *the plague of slugs* approach! I’ve collected buckets of hard-shelled snails for the ducks at an avocado/lemon orchard on the central California coast – as part of my first-light dead-heading in the hilltop rose gardens. Later we let the ducks out to forage all day on their own – with a child-wading-pool set out for them under an overhanging tree, to screen them from the hawks – so nice to see them resting in the grass together. They always returned to their pen in the late afternoon, before the coyotes started talking.

  2. This was such an interesting article to me. I plan to get 2 baby ducks in April. Thanks for all the info on how to train the ducks to eat the pests!

  3. Bravo! I really enjoyed this article. The information is very helpful, especially the fact that you differentiated between the duck breeds and their preferences. Thank you for sharing your past unsuccessful experience. I’m glad you were willing to give it another go with a different breed. Excellent pictures, a very enjoyable, interesting article that I plan to put to work in the near future.

  4. Thanks, great article. We tried Pekings and had similar problems. We didn’t do a lot of training, but it seemed at first we wouldn’t need to as they were slug hunters when young. As they got older they became more and more complacent, and just wanted to be fed instead of put in effort. They also would eat garden greens on occasion.

  5. Thanks for the info – maybe I’ll get two runners next week – I saw two advertised today – just before the slug season starts!

  6. Very well timed post! I live in North Wales too and last year was such a disaster for vegetbles we have got to the point where we are seriously considering ducks. As we have hens and get enough eggs I was thinking along the lines of just 2 ducks. Good to know that works for you. We had ducks quite a few years ago but the fox got them all because we found them very difficult to shut in at night; especially round the longest day when we were ready for bed before them. There are only so many times you can chase them round the duck house at 10.30 at night before giving up! We were thinking of positioning a house at the edge of a pond so they would have to swim in (idea taken from fox/duck filter described on this site). If they’re not keen on water do you think this would work?

  7. Dear Louise
    I also read about the duck valve, a great idea fortunately we don’t have a problem with foxes because there are lots of dogs around and our ducks are easy to put in. But still there is always a risk and it does play on my mind. Therefor i would like a duck valve as it would mean that i wouldn’t have to worry at all about locking them up at night. To be honest i cant imagine that my ducks would go for it as they never go under water. But perhaps you could teach them to do it. I am thinking of creating a hybrid between the khaki Cambell and the Indian runner for this reason. Although i shall experiment first with training the ducks.
    Best of luck

  8. Win win situation,especially eliminating the serious problem of metaldehyde poisoning of dogs (a major worry with pellet control of slugs).Bet the eggs taste good as well !

  9. Really interesting article, full of detail. Thank you.
    Can you tell me – do they trample the small plants when foraging?

  10. Thankyou for such a lovely,interesting guide to raising Ducklings,you make it sound so relaxing & easy. Getting a couple of week old runner Ducklings tomorrow & need all the good advise I can get.xxXxx

  11. What a fantastic and detailed story on my favorite birds, I very much enjoyed reading it, thank you :-)
    I would just like to point out that Indian Runners actually do love water, and swimming … um … like a … well … like a duck to water!
    With my very first Runners I didn’t have anywhere for them to get into water, so I provided them with a little kiddies plastic pool. They would be eagerly diving into it and splashing around as I was just starting to fill it up. They come back to the water continually throughout the day to splash and guzzle. They snort water in and out their beaks too, to clear things out – very funny to watch (and messy).

  12. Thank you for the information on the Indian Runners. I read this blog after ordering 8 three day old hatchlings, 4 males and 4 females. This breed seemed perfect for my property with a flowing stream, lots of irises and reeds that attract snails and slugs. On the downside, I also have three hawks that hover each day so the (now 2 month old) ducks cannot roam freely outside of their enclosure. At first, they stayed primarily in the duck house with a small run that was open to them during the day. They make a mess and it is important to be diligent about cleaning the area so that flies and rodents are not attracted to spillage from their food and water. Moving as a group, they seemed skittish and nervous, spending most of the day sitting on shavings and hay in their outside run. Last weekend, I extended the run to the stream with a 25′ x 25′ shaded enclosure with an overhead netting. Well, I would say that the runners don’t like water, THEY LOVE IT. They are so happy and playing games chasing one another in and out of the water all day long. They eat the duck week (a big problem for the stream) that passes through and even sleep in the water as a group, just floating on the top in a beautiful tranquil cluster. I collect the slugs for them after a rainy day, as a treat. I love these ducks. Again, thank you for your post and sharing your experience with raising these birds.

  13. An effective strategy against slugs, but what about worms? If your garden is depopulated of worms, because runners love those, too, wouldn’t that be a loss for the health of your soil?

  14. I’m sorry but 1) Those are not ‘baby worms.’ They are Enchytraeids, commonly known as pot worms, which are harmless but indicate your worm box is has an acidic pH and overly wet conditions, which pot worms like but red worms do not necessarily thrive in and 2) feeding processed breads, pastas and pastries to your ducks is junk food, high in carbs but low in protein. In the wild ducks do eat wild grains which contain more protein and lower carb content, but giving them processed grains should be limited ‘treat-on’ practice to prevent malnutrition. I’m especially concerned as you say your ducks do not like greens, this is unusual and probably stems from feeding too much bready foodstuffs early on and they have become picky. In general ducks love vegetables, greens and certain fruits, provided they are appropriate, safe and cut into small chunks, but should be researched as certain veggies must be given only cooked or only raw. For the health and longevity of your birds, it pays to research this. Good luck.
