I have 5 pullets, 2 of them get upset when im petting or holding one of other 3 pullets. By upset i mean glaring at her, trying to peck, and being vocal. I am wondering what is causing this, all 5 of them dont mind being petted or held, but these 2 have issues when someone else is getting attention. They aren't vicious or anything, once i stop petting or holding the other pullet, they will stare at her, might try to peck her/do peck her a couple of times and then go back to what they were doing. The other 3 hens are under these 2 in the pecking order, because they will lower their heads and themselves a bit when this happens. I don't see why they should have an issues with me petting or holding them though.
