Ok weirdly enough MY problem child is Matilda (and EE) and one of the girls she is pecking is named Margret! Ok ok well Olivia has been the most pecked. But anyway I have just ordered these Pinless Peeper things to help the feather pulling issue. Maybe they would hep you to? Supposedly they can still get on the roost and eat and all the other normal chicken stuff so maybe it would be at least a deterrent for her bratty behavior. I dunno Im a rookie myself but Im trying this. Just waiting for the mailman. http://www.eggcartons.com/Pinless-Peepers/productinfo/PINLESS-P/
