Had a broody chicken and nothing could shake her from it, tried cold water, locking her out of the next box. So let nature take it's course and after two months, she's back to her old self and her comb is red again. However, we've been away for a week and had parents feed and let them out, etc, but came back and she has literally no tail feathers left! Just a little stump. Not bloody, and none of us have seen either of other two peck her, but clearly something's going on. Anyone else had this?
