One of our red Sussex hens started limping about five days ago. Her right leg is the problem, and her right foot is turned in almost 70 degrees. Got progressively worse each day. They are all 2.5 years old. She now won't even go up the ramp into the coop now. Should she be separated from the flock? Should she have aspirin? I could build another little room within the coop to keep her separate but close. Not sure about that? Perhaps put her in a small cage in the garage? I can post pictures if that helps. A small video?
