I have recently netted my run due to extreme hawk problems. I am also integrating a dozen new pullets (about 8-10 weeks) into my much reduced flock of 7. They spent their first night together yesterday. I found one of the young pullets half bald around her neck and left side back and her left wing severely damaged and hanging. The missing feathers appear to be cut off and not pulled out (stubble and quills still there). Is this a different predator or did one of the older hens do this? There is no sign of any other creatures being there, the run is fenced to 5 feet and 2" net overhead, no signs of tunneling. The bird is in pretty bad shape, Is this from another hen or hens?
