My rooster is about 2yrs old. He has had a limp since he was iddy biddy I noticed it one day. Today I noticed it has gotten worse just since maybe 2 days ago. Yesterday I noticed he wasn't feeling well and wasn't himself. He was just hanging around not going with the hens which is RARE. Today I noticed his limp more and he was acting more not himself than yesterday. When he breaths he opens his mouth to take breaths. He is eating and drinking not moving about hardly. His poop is really green and yellow. There isn't really a need to post a pic. there isn't anything to see. can anyone tell me whats going on with my sweetie? thanks
