Cockerels and roosters are great but the relationship you have with your hens would change.
The hens would eventually become his hens and that inevitably causes problems.
The other concern is despite you having a wonderful run, I think you would find that it wasn't big enough with a cockerel as well. Everybody seems to need a lot more room when the boys turn up.![]()
I cannot agree more with @Shadrach When my wife pushed me to keep Jabber, she loved him so, I had to alter my relationship with Patsy and Lilly. They did not understand why they could not hang out with me anymore. I struggled because I simply could not sit in my yard and watch them. They would come over to visit and then Jabber would go off. Patsy and Lilly never "accepted" him and he clearly resented me for it.
My relationship with my flock will not permit a rooster and I value that relationship too much to change it. I understand this now and will not ask a cockerel (should I ever get another one) to grow up in this environment. He will be rehomed early.
I believe that the best roosters grow up with another rooster to show them the ropes as well. Jabber did not really have to earn his time with the ladies, he just took it when he could. I think he would have been a lot better rooster if he had to earn his time and learn his job from an older man.
