I currently have 12 JG pullets 2 JG cockerels and 1 true blue whiting cockerel. I know that's too many boys. The true blue is getting culled today. That leaves the two JG cockerels. At 21 weeks I haven't had any issues with over mating of the pullets. As soon as any of the cockeerels try to mate one of the girls, another cockerel immediately knocks him off.my largest JG is the alpha, the true blue is the beta, and my smaller JG is the lowest in the pecking order. Once the true blue is gone I'll have 2 JG cockerels. Is that too many for 12 pullets? I want the girls to eventually hatch out some chicks.
