Marcy,
I agree with Wynette, that's a low protein problem. Mine all just got done molting, and my pen looks like a pillow fight ensued. I have one snippy hen in my flock that will go after every girl in there from time to time, and pull a feather or two, but have never had a picking problem. I feed mine a mixture of Chick Grower 22% (non-medicated), mixed with Layer Crumbles 18%, and this time of year I throw in some wild bird seed mix with BOSS. Mine also get fed some high protein dog food 28% once or twice a week, mixed right in with their feed or fed as a treat. Pumpkins, bread, free range, oats sometimes, and I also throw in a bale of straw. I don't distribute it, I just toss whole bales, or sometimes whole flakes in there and let them sort it out and distribute it. Keeps them busy for hours! I think they really enjoy the whole bales the best. It makes them think they are doing something naughty, and they climb on it and peck at it and scratch at it until it all breaks down. I "scold" them when I come back into the run, and they all get this evil little twinkle in their eyes, like heheheheh, we did it! They get the benefit of the seeds and the exercise that goes with it. I think you are wise to cull out the perpetual pickers. Maybe up the protein first and see if that doesn't cure them, but if not, OI would cull them out too.
