I have one flock that has 4 roosters with 14 girls. I watch carefully for over mating. It hasn't happened. The roosters are under a year old, so technically, they are cockerels.
One of the guys has two girlfriends that he mates with. No one else is allowed to touch them. Period. If his girls won't put out, then he will try to other girls and his girls immediately put out. Immediately.
Another guy has two girlfriends. He protects them fiercely. Sometimes will try to do other girls.
The other two cockerels have 10 girls between them.
Not all boys are horny 24/7.
I have a cockerel with a girlfriend. They mate maybe once a day. He doesn't have access to any other girls. He's just not too horny.
It COULD work - but you have to be diligent about watching for over mating. From about 4 months to 12 months is the "puberty" time for the boys.
