So I'm almost convinced that my rooster has an ear infection. He keeps scratching at it and that could cause a loss of equilibrium. I'm going to give him a round of antibiotics and see if that helps at all, you might try it just in case.
I just noticed today that my BLR wyandotte cockrel was walking around with his head tilted to the side. When I went to pick him up he sat down with his head looking straight up. I've only seen wry neck in new chicks, never one this old. Has anyone successfully treated wry neck in an older bird...
