Welsummer picking at the others...

[McChooky]

Hi! We have one Welsummer and three others. Two are Easter Eggers and the other is a rescue that I'm not really sure about - seems like an EE though. Anyway, the Welsummer picks at the others. Not really like a bully but picks at their necks and is currently picking at one who just got re-introduced after a hawk attack. They have a completely enclosed run attached to the coop and another area that now has a chicken wire roof covering the entire area. They've got various things to roost on and hide under. I don't think it's boredom. The Welsummer has generally been top of the pecking order. My question is, would getting another Welsummer be helpful? Thanks!!

Chickens instinctively peck sick and injured birds to protect themselves and will kill one returned too soon.If the feather pulling began after the predator attack its likely related
