I've got 2 pullets, 8 months old, that have 'broken off' feathers along their necks. I thought the rooster was doing this, but tonight I went in after dark to get eggs and there was one of them with her beak nestled in on the neck of the other. Was she eating the feathers? I looked at them both for bugs but didn't see anything odd. Skin looks okay, maybe they just nuzzle together and this happens? They have free unlimited access to layer pellets all day long and every morning I put out a pan of fermented flock raiser feed. Does this behavior stop on its own, do I just monitor or do I spray some blukote on them to stop it?
