My roo Eddie carries his head and neck turned to one side most of the time, he's not eating or drinking enough but some. He has a hard swelling under his eye. He pants after drinking water. He's weak and has poor balance. It looks like because of the swelling under his eye, he can't see, so he kind of walks circles backwards sometimes. But he can walk straight. It seems like he carries himself so crooked because there is some pain maybe somewhere in his neck or crop. His crop has been small and firm and his stool is greenish and dry. Please help!
