anyone had a successful bachelor flock?

thats pretty much the whole question, ive grown up with chicken my whole life but ive never seen anyone actually try a bachelor flock. ive heard people mention them though. i love roosters, and having a flock of just roos sounds great to me. ive been wanting to do it for ages. is there a certain number of roos you can go to before they start fighting? and how far would my hens have to be?
