I have a pullet that we call Pecky because since the day we got her, she pecks at everything. Should have taken her back. Her pecking has turned into feather plucking. She does it to all of the hens. They have a protein rich feed, fruits and veggies, plenty of space. I am going to try separating her for awhile. I looked at other threads and there doesn't seem to be a whole lot of advice for this.
