We recently got a Roo and hen from different sources (about 2-3 weeks ago) full grown, rooster is missing his tail feathers (people we got him from said he plucked from being confined), they look like there growing back though. Hen looked in perfect condition, I just notice today that she is missing feather on several parts of her head. Could the rooster be picking on her or is there another cause? It was not like this several days ago, last time I got a good look at her. I took pictures.
