You'll have to do something. Your hens will be ganged up on and that's pretty horrible. You'll need over 20 hens usually to keep three roosters happy, plus lots and lots of space. Much easier to get rid of roosters.....you can still get more hens just because.
I see a pair--male on top, female on bottom. It's not a cross that sounded too appealing when I read the title, but I'm liking that hen!
Welll............enlarging the pic, not so positive the second bird is female. I think I'm seeing some hackle and saddle feathers starting there, and those...
