My hen who is about 5 months old was seperated from the flock 2 days ago because she was just laying down, not moving unless she had to and then more like hopping or wobbling off to one side. I've tried EVERYTHING I can think of, I've never had "chicks" so really have NO IDEA. She seems healthy, good appetite, but squawks quite a little bit and can stand for a few minutes but cannot walk, she hops on the part where the leg connects to her body. Does that make sense? Any idea what it could be and how I can help her?
