We just found our RIR decapitated and ripped open in our coop. My husband thinks it was a hen fight but I can't believe another hen would be so vicious. We recently added 2 new hens about 3 weeks ago 1 being a large bardrock. We found both feathers in the area of the fight. I can't believe my bardrock did this. We have a large population of hawks in the area but the only thing missing is the head. I say predator....but just in case has anyone had a hen be that brutal?
