So one of my RIR is starting to bully one of my Buffs. Up until now, everyone has been fine, no one is currently injured or sick. Hens are about 6 months old. Yesterday, they seemed fine. Today, Little Red is really going after Honey, seeking her out and chasing and pecking her comb. She doesn't seem to be bleeding though. Little Red doesn't seem to be attacking any of the other hens and the other hens are not attacking Honey. Maybe just some beef between the two of them? Is this just a pecking order situation and should I let them work it out? Or should I separate the aggressor, Little Red?
