Controlling Worms in Your Flock

There’s a divided opinion on worming flocks; some keepers send faecal samples for testing and worm, or not, based on those results. Most adopt a quarterly worming regime alongside their regular manual checking of the birds, here Clare Taylor (aka The Chicken Whisperer) discusses how to support gut health alongside a dedicated worming policy.


How are my birds infected by gut worms?

Intestinal worm eggs are left in grass in wild bird droppings, they are then eaten by our free ranging chickens, where the eggs start to hatch and populate their intestines.

How do I worm my flock?

Advice should always be sought either from a vet or a suitably qualified person (SQP) at the point of purchase of any worming medication.

As a guide, you should worm your flock every quarter for optimum health and productivity using a licensed wormer or a medicated wormer premix (where the wormer is mixed with feed or it is contained within the manufactured feed/pellets), which can be purchased from any licensed outlet or online. You don’t need a vet prescription. These wormers do not require the withdrawal of eggs from human consumption, and advice on their use should be sought from an SQP at the point of purchase for the use and administration of the product.

What about herbal products? 

There are various herbal based gut conditioning products available, such as Nettex’s Herbal Gut Conditioner.  These work by helping to optimise the gut microflora making the gut less suited to intestinal parasites, but they should always be used in conjunction with a worming programme using a licensed product, as a heavy worm load can kill a hen.

It is a good idea to support your flock’s gut health by feeding Nettex’s Herbal Gut Conditioner regularly, and adding Nettex’s Mineral Boost Powder to their feed once a week, but this should not be relied on to control worms.

How do I keep worm eggs to a minimum?

Even if clear, waterproof covers are used on all of your chicken runs, the litter inside will still become damp and become an ideal breeding ground for intestinal worm eggs.  This is why it is so important to treat the ground as well as the birds in order to minimise re-infestation.

Once you have completed your quarterly flock worming treatment, clear the run of litter and sprinkle the base with Nettex’s Ground Sanitising Powder.  This will help clear the ground of worm eggs and bacteria, and should be followed by laying a good clean layer of quality litter, re-applying Nettex’s Ground Sanitising Powder and rake through on a weekly basis for optimum results.





Full control of gut worms in your flock cannot be achieved without the use of a licensed wormer (or medicated wormer premix) and it is advised that you seek advice from a vet or SQP.

Should you have any doubts about flock status or using a wormer – don’t rely upon visible worms in their droppings to determine if they are infected. Most gut worms aren’t easily visible and by the time you can see them, the worm count will already be high.

Support gut health year-round, using a dual product approach with Nettex’s Herbal Gut Conditioner and Nettex’s Ground Sanitising Powder. This may help optimise your birds’ health and productivity alongside a suitable regular worming programme.
