For the past two weeks I have had one of my 11 week old hens quarantined from the rest of the chickens. When I found her in the coop she could not walk. She was the same size as the rest of my chickens. Two weeks later she is drastically smaller than when I quarantined her. I checked her legs and her wings out when I quarantined her and throughout but it does not seem to hurt her. Still she can’t walk or maintain balance. I don’t know if this matters but she is a Copper Marans.
