After reading this last couple of pages... Do my birds have mareks in them? In the last year I've lost two birds, one was eight weeks, and became lame with her toes curled in, could barely use one leg, but the other was immobile. Was lethargic, and didn't eat of drink much, the last day before she died, her poop was really green. The next bird was 20 weeks, and went lame, even though she still tried to get around, the other birds bullied her, by three days she could barely move, and thinking it was what the other bird had, I culled her. Her eyes were blue, but had been that color since she was a chick. Could it have been something else? If it helps, they were of the same breed, and half sisters. I also lost another one at a week old, but she was just a runt that didn't survive.
