I have a rooster who has injured one leg. The injury appears to be in the upper leg/thigh and is possibly a dislocation, although I think it's just badly wrenched. He's very eager pursuing the ladies in the morning, and my best guess is he's injured it going to or from a perch. A little checking on here and a few other places, and all sources say this kind of injury needs a vet visit. He's perfectly healthy otherwise and one of my favorites. We have 2 large animal/farm practices near me- and I was surprised to discover that NEITHER will treat poultry. They referred me to two local avian vets, and both of those said no as well! they only treat 'pet' birds, I pointed out that I thought any bird that some one was willing to pay a vet bill for should be considered a 'pet' in my opinion- I can't believe there's a phone book full of vets in my area and not a SINGLE one will treat poultry!
