honestly she would probably be fine once she's mature. I have a pair of lil Japanese bantams that get mounted by a rooster who's practically a standard male and they're fine as long as he does the deed and them gets off. Just want to make sure the small hens don't become his favorites
Being in a separate space isn't guaranteed to make him more docile. I've had my share of roosters that I housed seperately, either within a coop or without other hand nearby that still would have loved to take me on
