One of my BLR boys has got a problems with his right leg. He tries to walk on it, but all he ends up doing is stepping lightly enough on it to get his other foot forward. I've checked to see if the tendon may have popped out of place on the hock (it hasn't), felt to see if his hip is out of joint (it's not), and cannot seem to find what exactly is causing his pain. Is there a possibility that he's got a torn or pulled muscle? He's still eating well and isn't acting ill, it's just he's not wanting to move around too much, even though he's wanting to stand on it. His mobility is causing him issues outside...one dominant cockerel keeps trying to do his business with him, and I just had to pull my tom turkey off of him for the same thing. He nearly crushed him!
Any thoughts as to what his problem could be?
