I'm posting this for a friend of mine who just called me. Her roo (about 7 months old) was found an hour ago, laying on his side, unable to get up, with his head wobbly and on the ground. He has trouble breathing (beak is open, and he's gasping), and his crop is completely empty. He was in the run with the other chickens all day. What could be wrong, and what should she do? Please help, she's waiting for me to call her back!
