Backyard Fowl Keepers

Are you sure they are worms and not fly larvae (maggots)? Sometimes, poop that sits outside for a while can attract flies, and their larvae may be mistaken for parasites. Try checking fresh droppings to be sure.

I've had this happen before, and I treated my flock with Valbazen (Albendazole). It worked well! Just make sure to repeat the dose after 10 days to catch any new hatchlings.

If one chicken has worms, it's likely the whole flock does. You may want to treat all of them to be safe. Also, consider cleaning their coop thoroughly and rotating their run to reduce reinfection.

Worms can weaken chickens over time, leading to weight loss, pale combs, and lower egg production. If your chickens show any of these signs, treatment is important. A vet visit could also help determine the best approach.
