I walked out to my run & found one of my 7 month old BOs laying in the hay while the others were up & about. I threw in some BOSS & the rest of the hens went crazy pecking around, while Priscilla just sat there, staring blankly. I went in to the run & she stood up. She is all fluffed up & her tail is almost tucked between her legs. Her comb is red & bright, her legs & feet look good (no bumblefoot). I felt her bottom and it feels soft & pliable so I don't think she is egg bound. She walked a couple of feet & just stopped & stared blankly again. I brought her inside & checked her out again. Nothing seems physically wrong with her. I checked her bottom & she doesn't appear to be plugged up. Currently she is in a dog crate in my basement. I have hay in there with some water & yogurt. The room is dark. Any suggestions?? Am I missing something? This is my first year with hens & my first real "illness." I would appreciate any advice!
