Lethargy and yellow poo in turkeys often means Black Head. It's a dreaded disease. Usually starts out with their feathers looking ruffled and then just laying around Alt instead of foraging. By the time you see yellow poo,is often too late. I have saved a few that got to the yellow poo stage but it took work and money. I gave them a regiment of safe guard goat wormer and fish Zole. And I had them on high protein chick starter. Black Head can live in the soil for 7 years and turkeys often catch it from chickens (chickens are usually immune) if you have more turkey, you might want to read up on Black Head and get them wormed. After worming,you need to give them a round of Fish Zole antibiotic. The Black Head parasite isn't what usually kills the turkey, it's the secondary infections such as Coccidiosis, Worm overload, and some other nasties. Your local county extention agent should also be able to tell you if there is a prevalence of it in your area. Lots of people have kept turkeys and chickens together, but Auburn University recommends keeping them seperated by a few hundred feet. Please Google "turkey black head", it could save your flock.
Edit: I almost forgot, raspy breathing is another symptom. Even if they don't have black head it won't hurt to worm them. And the Fish Zole is cheap compared to the cost of losing turkeys. It also won't hurt to put them on a high protein chick starter wieth amprolium as a Coccidiosis prophylactic.
