when i am kneeling and rubbing a chicken or checking one over i have one chicken that will watch, run over and try to attack the bird i'm working with. she is never really mean to me though besides of course a peck or two. and since im getting close to integrating my two sets of chickens i brought one of the chickens over to look throught the wire of the run to see what they would do. they bunched around and stared, making noises and then all of a sudden the one chicken turned and started to peck at the ones that shes always been with. i would have thought she would have pecked the new one i brought instead? does anyone know anything about this? shes never ran after me or been mean, just occasional things like this.
