At work we have small demonstration flock consisting five dual purpose laying pullets coming into lay and a Barred Plymouth Rock cockerel in addition to a pair of American Games I provided. All are about 5 months old. Barred Plymouth Rock cockerel has taken to attacking one of his keepers but ignores everyone else. For last two days he has flogged and chased her. Tomorrow I will try to film the debacle and try to get those parties to break cockerel of attacking without employing violence or restraint against him. I will also be chewing some butt when comes to how birds have been interacted with. Kids have been instructed to chase birds and keeper being attacked has alternated between kicking cockerel and running from him. Another party has been directing the kicking at the bird which works for him because he is also confident in his mannerism while doing so. I also intend for them to re-tame birds I provided as they now avoid human interaction which decidedly different from all of my birds kept back. This is all a husbandry / management problem.
