That's what all parents say.
With many cockerels it's a stage and they and everyone elses puts up with it until the cockerel makes a serious attempt at displacing the senior rooster.
It can be a rather long stage unfortunately and the keeper needs options and the more space one has the more options there are.
I had eight coops of various sizes spread around at one point in Catalonia and still found I was short of space with 30 or more chickens from single males to broody mums.
Predation helped. Extremely sad at times but effective population control.
Even with the space and the predators with all the hens going broody at least once a year the possible rate of growth should be obvious.
You can not let the hens hatch, that's one option.
You can limit the number of eggs in a clutch. If one knows roughly how many one loses each year, adults and chicks then one can at least attempt to keep a stable population. Free ranging one tends to lose one at a time rather than the flock slaughters one reads about with confined chickens.
Again I'm talking about free ranging on rural acres, not out in a quarter acre plot.
One can only give away so many.
Eventually one is left with having to kill some and I think one should eat what one kills whenever possible. Let the hens sit and eat what one cannot afford to keep for whatever reason.
I have no other coops available. I am not opposed to butchering and consuming any "extra" birds (better than eating the supermarket meat, IMO). Right now the Tsouloufates are not self-sustaining, so all their hatches are incubator hatches. I'm raising quite a few chicks right now (some intended for breeding use, some for meat) some of those very possibly carrying the son's genes. While he is (conformationaly) a better choice, I'm not a fan of his behaviour. He is now 9 months old, but I will most likely not wait till he matures more. They have about an acre of free range space, but that doesn't seem to make the situation any better for the hens. Miss Mayhem truly resembles her name right now
