My Houdan managed to get over the fence yesterday. When my husband got to the neighbors yard, their dog had her cornered. She was on the floor feet up. Her tail feathers are a bit of a mess. She was not bleeding and appeared to be ok. This morning. she was slow to get out of the coop. I watched her stumble from the roost. She then stumbled out of the coop. She is moving really slowly. I can't see any obvious injuries. I am new to chickens and don't know what to do for her. Any suggestions are appreciated.
