Hi I had a 7 month old light brahma hen drop dead. She had been laying as far as I know, but I'm not sure. I have 2 others that look the same and I can't tell them apart. I think it is the one who was making this funny noise. She had been doing this high pitched squeak now and then, (maybe a cough?) since August. She had no other symptoms. None of the other chickens have had any symptoms, or made that noise. I'm pretty sure it was her that died. She is a heavy, healthy-looking bird. We are wondering if it is safe to eat her? She has been outside in a safe area hung upside down since then, and this is Michigan, so she is frozen with all her body parts intact, though I did drain what blood I could at her neck. Hate to let a good chicken go to waste, but don't want to eat her if it's not safe. Any thoughts? Thank you!
