Worming Chickens

Chickens need to be tested for worms regularly. If there is a build up of worms in their digestive system that can cause health problems. Keeping chickens in a fixed area as so many of us do, where they are grazing the same piece of ground continually is the worst case scenario as they will be contaminating the ground and picking up worm eggs as they are feeding. Infected hens shed thousands of eggs in their faeces onto the ground and so, the problem gets worse.

How can you tell if they need worming? By using a Worm Count Kit! Using a kit means you’re not worming chickens unnecessarily.

Wormers

I use a product containing Flubendazole when necessary to worm my chickens. This is a proven chemical wormer that kill all common worms and their eggs in the chicken and is the only product licensed for use in chickens feed. In between these times, I use Verm-X which has approval for use in Organic systems – now this is a herbal product which works in a different way – you will need to feed this to your hens every month for it to work. The really great thing about Verm-X is that being herbal, it contains many ingredients that are good for your birds so it can improve their overall health.

Good Husbandry

Practising good husbandry techniques is key, in between worming chickens. We try to rotate our birds grazing area every month so that they get some fresh grass but so the ground also gets to rest (this is one of the major principles in Organic farming) and we  keep the grass mowed short which allows the ultra-violet light from the sun to reach droppings and kill off worm eggs.

cleaning run

Cleaning a chicken run by raking droppings during dry weather.

General cleanliness is of course important so if your chickens scratch around in their own droppings, you should be thinking about cleaning them up, rather than hitting them with a regular dose of chemicals.

Bad Infestations

If you have a bad infestation of worms, you do need to keep in mind that eggs deposited on the ground will re-infect your birds and it is necessary to repeat the treatment before the eggs hatch and grow into adult worms to lay more eggs. This takes 3 weeks for most common worms carried by chickens so I would re-treat after 3 weeks if I suspect a particularly bad case of worms.

Where external parasites are found on the bird (such as Northern fowl mite or lice) a systemic wormer / pour on product containing Ivermectin is useful. This kills a more limited range of worms. Victoria Roberts Diseases’s of Free Range Poultry says it excludes tapeworm and fluke, but these are less common in chickens. It isn’t licence for use on poultry so you would need to go to your vet for their advice.

Please remember this should not replace the advice of a qualified veterinarian who can advise you about worming.

  1. Hi

    Please can you give me some advice, I have just bought two chickens which I noticed had a roundworm in one of their poo’s. I have ordered the Flubenvet but our chicken coop is on paving slabs and has a fenced run around on mud is static. Please can u advise me how to treat the area or is it best to treat chickens twice?

    Thank you

    • I would re-treat after 2 weeks to make sure you kill the worms that hatch from eggs that will re-infect the birds. I would also try using a ground sanitising powder on the mud run – this is basically lime and is an old fashioned method of sterilising the ground for worms and their eggs as it dehydrates them.

      Next, I would add a substrate to the run – eg wood chip (not bark..) or sand / gravel. This can be changed periodically when it gets messy and helps to remove any further eggs / worms.

  2. I use diatomic earth to worm my cats (sorry just reading your site, don’t have chickens) and it works really well, I get it of eBay and its around £12 for 2 kilos of human grade.
    Not sure if you can apply this to chickens but worth a try..

  3. I have some 11 week old chickens which I will eventually introduce into my laying flock. Should they be wormed and if so is the dose per kg. pellets of Flubenvet the same as for the older hens?

  4. hi 1 have diatom earth in my coop at all times will this help as a wormer for my chickens or will I have to put it in there feed they peck the floor of the coop
