I have a hen that I got a few months ago. Ever since day one, she has been kind of scruffy looking. Missing outer feathers and is mostly covered by her downy feathers her wings are very small I think because most of the end feathers are missing. She has a red face and comb. Eats, drinks, lays eggs etc. Roughly 2 years old. Again since day 1, she has done this high step thing when she walks. Not every step, but pretty often. Pulls it the leg right up tight to her body and then slowly lets it back down. I have even heard it snap before like a joint cracking. Does anyone have any idea what this is or?
