Did you know that coccidiosis is species specific? Chickens get 9 or more types, turkeys get 7 maybe?, ducks get another set, same with geese, and peafowl get their own types as well. It might be possible for some crossover, but I think it's quite rare.Yup, and alot more problems with cocci.
The disease people really need to worry about when raising peafowl with chickens is blackhead.
