Yes, that would work fine, I think. Separate the coop with the chicken wire and that way he can't mate, but the pecking order won't be seriously disrupted if you put them back together.He has four hens with him as of now and two he can mate.
In a few days, he will have his other girl and four chicks
So soon he will have seven he can mate.
Good idea, hardware cloth dividing a area of the coop? I’m thinking it might be a good idea to seperate the ones he can mate with him and separate the others. Would that work?
Four hens is really not enough for an active, small breed rooster, and that is probably at least part of the problem. Ten is about right. But I think giving the hens breaks from him will help a lot.
