I purchased an ameraucana young rooster about 2weeks ago and he was severly malnurished and underweight. I have been giving him electrolytes in his water and he has been drinking and eating regularly. However he still has been pooping very watery and he hasn't gained any weight. What can I do to stop his watery poop and put some weight on him? Also my female hens keep pecking at him and chasing him constantly, but I'm guessing its because he wasn't raised with them and hes an outsider to them.
