I wonder what's wrong with my Buffie. She is old, at least 8, and was the flock leader for the last 5 of those years. A good hen. Now she's gone all lethargic, sits under shrubs, can't stand for more that a few seconds. Brought her into the house last night and fed scrambled eggs and gave water with a syringe. She ate but won't drink on her own. One tiny poop, very dry. She is still talking to me and I want to do anything I can to help. Her sister is still going strong. She does seem to be in some internal pain. Advice?
