Last week I brought home my new pullets there are 73 of them. They are being kept inside away from my old flock (who have shelter also just not in the "hen house") I got a rooster with these hens......They've been getting along great and the "hen house" is huge big enough that they have room to flap and fly and run and get away from each other.......I just went out to do evening chores and lock up for the night and the hens were eating the roosters tail! I mean his tail was gone....not his feathers but his TAIL. and they had plucked his back also. Wasn't a huge amount of blood but some. I reached into the swarm and plucked him up and got him out and I was bringing him in the house to dr him and nurse him back to health and it was obvious he was in shock as he was shivering. When I hit the warmth of the house he stiffened all up and I looked in his eye and knew he was gone. Why would they do this?
