I have a had a true learner's year with chickens. I've lost an entire flock and I'm down to two that I have grown fairly attached to. My top hen started picking when I had a little hen that I rescued. She ultimately chased that hen out of the coop and a dog got it. It's down to just her and her sister and she is slowly pulling every single feather out of that poor creature. If I separate them - someone is going to be alone. If I cull her - her sister is going to be alone. I have various and asundry chicks and eggs coming this spring. My instinct is to cull my top hen before I put the chicks outside when they are big enough and hope poor Blondie can make it until then. Mind you - other than the stewpot, separation, and pinless peepers (which I am going to order right now) I have tried every picking remedy known in the last two and half months. Since she's now picking on her sister - I am thinking it's a compulsion and agression than I am just not going to be able to stop and if I introduce her to a bunch of other chickens - she is just going to show them how amusing it is and de-feather if not kill an entire flock in the process. Poor Blondie looks totally mangy all over and her bottom under her tail feathers and vent is bare. I am at my wit's end dealing with this bird - at this point I'm not even certain Blondie would be better off alone. Unless someone has a new picking remedy - what I am really looking for here is for someone to confirm my thought that this bird shouldn't be moved into my new flock (where I would assumed due to her size and agression she would be the top hen for awhile as well.)
