I have a new cockerel recently added to the flock. Now, when I first integrated him to the main flock, he had been isolated with his other flcok member cockerel, for about 5 weeks. I was dealing with them, 1:2. When I put him in with the others, my status to him changed. Nothing else. He seemed to want to dominate me as being under his level in the pecking order.
Now, I have 2 great adult roosters also in the main flock. We all get along just fine. I let them keep their distance from me, and they have never tried to flog me. But this new young guy, he was thinking about it.
So, I stepped back out of the ring/run. I let the big boys handle his training. He needed to learn his new place in the flock pecking order, without my being in the picture. I would interact as little as possible with the flock while he was getting his own training. He has mellowed considerably now.
This is just my own experiences, mostly led by observation. I have learned much by reading on byc..and beekisseds posts. I tired at first using the dominant postures......pole, chasing, holding.....but I was seeing more success by letting the roosters train him.
I noticed yesterday, his full red single comb was bloodied up. He must have been feeling frisky yesterday, and got thumped for it.
I have also noticed, with cockerel integration, that the youngest cockerels, are NOT allowed to crow. That is a priviledge for the head roosters apparently. The ones with the hens. The cockerels are destined to stay subordinate below the lowest pullets. In eating, scratching places, dust bathing spots, roosting spots and territories. At night, when they get their evening FF, the one lowest cockerel, stays away from the food till the last pullet has ate and roosted. Only then is he allowed to come inside or to the food.
It is all just interesting, watching this chicken drama.
On a note; The RIR cockerel accidentally escaped the run yesterday, when I was putting the main flock back in it. He realized he was out, but wasn't sure what he was supposed to do next. I grabbed their scoop of scratch bribes....and he followed it right in. When I integrate younger birds, and new birds, I generally won't allow them to free range until I see they are more fully integrated and want to go back into the run. He's not quite there yet.
