One of my friendliest buff orphingtons has started acting very strange. Orphingtons usually have this soft groaning sound when wandering or interacting. This one is just saying cluck, cluck, cluck and fluffs her feathers all out anytime another hen gets near her. Feather are fluffed, tail spread and wings dropped....like a Tom turkey. It is comical, but should I worry? She is still laying and running around eating, not nest sitting like a broody hen.
