I have a Polish hen that recently had bumble foot. Did the surgery, and things were going great. She was out free ranging, on top of the coop after two days, her fav spot to sleep. Yesterday when I got home from work, and went to grab her to change the bandage, I found her on the floor of the coop laying down with her head upside down like wry neck, but she's 1.5 years old, so I suspect brain damage. I have her in the house in a cage, got her to drink water, but her head is still unstable, it just swings around most of the time and it seems like she can't walk. She did manage to lay an egg last night. Is there hope for her, or should I just put her out of her misery?
