I miss Flo something awful and still think about her a lot. She was very special. She was around five when she reached the end.
For those new to this thread, Flo was an EE hen who was a problem feather picker from the time she was just a few months old. I tried everything to curb the habit and finally concluded her brain was just wired differently and it made her compulsive about yanking feathers from other chickens. Finally, I had to segregate her, and she had her own enclosure in the run.
Judy, a Speckled Sussex, around five years or so, besides being the main picking victim of her three mates, was also a picker herself. Now, since she's been living with the main flock away from her three mates' influence, she not only is sporting a full complement of feathers, but she hasn't resorted to any picking, either.
Yes, the move is now permanent. Judy appears to like it just fine where she is. Sometimes, to solve the problem of feather picking, it requires creativity and drastic measures.
