As I was scrolling, I was thinking what Chickassan just said. Mostly wondering how big the coop is though. If space is at a premium, well... would you wanna be cooped up with three other ladies in a tight space? Like college all over again, fighting over the darn bathroom sink before class.
Missing feathers on the head is a little curious though. I'm used to seeing side of the neck and back feathers missing in pecking order spats. Hmm.
Sounds like Shelly is top bird in your coop.
ETA: Getting rid of Shelly most likely would merely transfer the undesirable behavior to whomever replaced her in the top spot. So not a necessary move unless aggressions spiral out of control.
