I am more and more impressed with this bloodline, if it is bloodline. HeiJ is currently 15 weeks old. He has 3 RIR hens, his sister who is two weeks younger than him, and 2 9 week old pullet chicks.
At this point in my experience other cockerels have been jumping everything in sight, refusing to take no for an answer and basically being teenage nuisances.
He's already tit-bitting and wing dancing. If one of them says no he can get quite insistent, but if they don't squat, he doesn't mount. He seems to be ignoring his sister and the chicks, which is exactly what I want.
His JG father had a brief teenage nuisance period, but he had an older rooster to teach him manners.
If this passes on to the third generation, I'm going to be celebrating.
