She's just not getting any better. She lost a LOT of back feathers this past summer from a bad roo.. and then the other hens were pecky, and she hasn't regrown ANY feathers. if anything, she's losing more. I've had her separated, additional protein, a sweater, and clean straw for months... well, the sweater was a recent addition. Her eyes have been half-closed for the past 6 or 7 weeks, which makes her look super grumpy. She's only a year and a half! Anyway, I let her out today, to mingle, and she was picking up her feet like they were on fire. It was really strange. Now she's sitting in the doorway of the coop, eyes closed, just looking miserable. I feel really bad, but I think I'm going to let DH finish her off, just cause she doesn't seem to be getting any better, and her quality of life is sucky. She still lays the occasional, wrinkly egg, but her vent area is all gross and dirty, she won't preen or anything... any advice? or is it time to let her go?
