I have been having an issue with one of my pullets picking feathers of the others, and this has resulted in two of them being injured. The chickens forage when it is warm enough, and are eating Nature's Best Organic Layer Feed, so I don't think a nutrition deficiency is the issue.I have separated the chicken doing the pecking, and I have read a bit about some cure where you put a bit of salt in the water. Does anyone have specifics on this, and have you ever tried it?
