Found one of my leghorn chick (5weeks old or so) dead in the brooding pen, in my garage. I thought she had broken her neck, because she was laying on her side and when I touched her, her neck feathers ruffled and she flopped around for a second and then died. I found what appeared to be pure blood on some of the bedding, but no one was bleeding. Looking closer, I just found this. Is it bloody poop?
