Welcome!
They will balance out by being killed off, not so nice for them. Your survivors will be the wilder and luckier individuals, and maybe that's what you are looking for.
I would fence and coop them in, and sort out who stays, and who leaves. You must have many more cockerels and roosters than is reasonable, so start there, and then remove hens as well, to get to the flock size you have space for and want to feed.
