Almost 7 year old hen started out a couple weeks ago stepping more carefully, progressing to lifting her legs up high and carefully setting them down to stumbling a little, then trouble jumping up on roost a few day ago to trouble keeping her balance, now barely able to stand. She has also lost interest in treats and food in general over those weeks to now not wanting anything. Her comb was just starting to redden up when this all started. Had not been laying because of molt then winter. Pooping slowly decreased also, of course, to watery, then diarrhea. In the last couple days I've tried many thing to try to help - abdominal massage, worming, checked for mites, ACV in water, crop massage, it wasn't full or swollen since she hadn't been eating much. She didn't come out of the coop today so I gave her a little water and cleaned out the diarrhea from yesterday - she ate a scrambled egg in olive oil I gave her and some water soaked bread and water soaked feed. So sad to lose this one, well, any one. Any ideas anyone?
