Can I separate a single rooster?

[cute chicks here]

More hens aren't an option right now. We are going to put the house up for sale and will be relocating them or adopting them to the new owners. It's bad timing.

This is happening with several hens, but 1 is really getting bad. She's not tiny and the rooster is the same size as the hens. They are all about the same size as the Rhode Island Reds. I'm wondering if anyone has experience separating a rooster to deal with something like this.

I have the same problem,my easteregger rooster is huge at 6months and he keeps mating with my elderly bantam cochen. I separated him yesterday. I only have 4 hens and he always goes for the small one.I live in town and am only allowed 4 hens. I hatched the rooster by accident.
