I had a buff like that last year... fox ate her. I felt bad she was eaten but didn’t miss her nastiness.I used to have a non-stop broody in the FL flock. I finally resorted to using the broody buster cage with a hardware cloth bottom and got some limited results from that. After being in that for a couple days, she'd seem to be over it but within a week or two, she'd be back to her old broody self. I gave up and re-homed her to a friend that said she wanted her for sitting on fertile eggs.
