I am hoping some fellow backyard chicken people can help me. One of my girls came down ill a few weeks ago. She started staying by herself, then had diarreha, and began doing a head raised opening & shutting of her beak...I thought she may have Gape Worm, since she wasn't coughing or didn't show any indications of discharge from nose or eyes. I treated her with Panacur, five dailey doses...didn't notice any worms at all, so also gave her 2x daily antibotic for 10 days. I brought her in the house & am keeping her in a penned area so I could watch her. She is doing much better, but still is very unsteady on her feet...like if you would give her a little nudge she would lose balance or if you pick her up, when you put her down she at first falls over,then ends up getting up. I tried putting her outside today after a week in the house in my heated outdoor coop with the other 7 hens. She started out fine, but within a few minutes, two of the hens had her pinned down pecking her vicously. She again could not get her balance...I think the other hens know something is still not right with her. I'm at a loss what to do know, or what could still be wrong with her? There are no bird vets in my area, and none want or can answer chicken questions. Any help this group can provide would be greatly appreciated.
