I have had my five free-range chickens since last September (1 year, wow!). This is my first experience with a sick chicken and I'm clueless. It is my sex-linked Buff Orpington who started being broody-acting off and on at about six months old or so. She had been what I thought being broody the past 2-4 days, and when I looked more closely at her today, she looked bad. One eye seems not just closed, but gone, and the other can barely open. When I checked her over, there seems to be feathers missing in the front. Her waddle and such are all shrunk up and she seems to have patches missing around her face. Where do I begin?
