Hi, my year old Ameraucana rooster has been walking funny all day (it's 8:41 pm). He's not limping, it's like he can't balance right. He's also panting a lot, more than his hens, which is sort of normal, as he's bigger. He's never done this before, but seems normal otherwise. He grooms himself, makes the food call, and watches for hawks. I can't post a video, because they're starting to get on the roost for the night. Please help!
