One of our pullets (3 and a half months old) is getting pecked real bad. We have 6 of them, and one or two of the flock is pecking this one pretty regular and causing her pain. We've sprayed her with blukote and also had her seperated for 3 days to help her heal (her feathers were growing back in already). What can we do to stop her from being pecked to death? Is there any way to fix the behavior? Thanks!
