My hen is walking oddly. She crouches a lot. What I mean to say is when she's walking she lowers her body closer to the ground. So it's as if her leg or legs won't support her or perhaps hurt. She is moving around as much as the others. But something is obviously wrong. I'd hate to think she is in pain. It's not like I can ask. So much can happen to a chicken's legs. Has anyone seen this?
