Rhode Island Red
QuestionRhode Island Red: I want to know some internal parasites that affect chickens and what are the treatments for those?
Answer Round worms would be the most common internal parasite. A chicken could have worms when you purchase them and spread the eggs through their droppings.
Hatchery chicks would not generally be infected due to living in brooders. Chickens have to ingest the eggs of the worms from the environment, usually scratching and eating near infected droppings.
Each type of worm has a different life cycle and responds better to different wormers. If a chicken is not treated, and possibly re-treated, the worms can grow large and make them weak and very sick.
Living in pens and coops with concentrated amounts of droppings can lead to a whole flock being infected.
Your local feed store will have chemical products recommended for your area. In order to get an accurate diagnosis of which type of worm, a stool sample would have to be examined by a vet.
I use an organic product, which has no withdrawal time after treatment. It’s called Diatomaceous Earth and there is much information about it on the internet.
Some worming products advise not to eat the meat or eggs from chickens treated for certain periods of time.
