My RIR alpha hen has become extremely aggressive in the past few weeks. She has completely plucked out all of the butt feathers of one of her fellow flock mates, and I noticed yesterday that another one is now missing all neck feathers and some butt feathers. I also spied her eating a shell free (membrane only) egg this morning and did find another egg in the coop that had been pecked. She has been making a ton of noise as well. She woke us up twice the other night and then at 3:30 a.m. with her extremely loud clucking. I am worried that she will kill the ones she has started plucking feathers from, and that the other chickens will follow in her footsteps. Has anyone dealt with this before? If so what did you do? If it keeps up, I am thinking she may make a good dinner. Too bad she is such a good layer.
