One of my RIR hens has turned into...I don't know what! If I put my hand down low to toss treats, or to put my hand on her, she pecks me...viciously! When I try to assert my authority over her she challenges me! Pecks harder, bows up at me, even uses her claws! None of my hens are laying right now and are molting some, too, so I don't know if her mood will improve when the egg laying starts back up, but if she doesn't chill out soon, she and I are gonna have a throw down! She is the only one doing this, so maybe it is a 'head hen' thing.
