I have a finicky scissorbeak black sex link hen named Thomas (my two year old named the poor girl). Shortly after acquiring her she ran away and evaded us for about a month before we captured her and introduced her to the flock. She's the black sheep of my flock of 7. Never really "made friends" with either of the two cliques. Hangs with the younger girls because the older ones can get pretty nasty to her. She eats and lays pretty well. Over the past week I've noticed her head feathers going missing. Is this likely a case of feather picking by the mean girls? If so, any ideas on helping poor Thomas out?
