Adding bantams to flock of LF

[dandrews1971]

I have a flock of 14 girls & a few young roos that free range most of the day. (2 of those roos soon to be gone). So far, not a single issue. Id like to give the bantam roo that I have a few ladies more his own size. I'M assuming the larger roo will attempt to mate them too?
None of them are aggressive, some squabbles but not a single injury. Maybe this is dumb. Can the larger roos hurt the bantams by mating? Would eggs be bigger than normal?

Your hen's can get hurt, especially when the roo is much bigger, and then on the other side, I personally don't like to mix bantams with bigger breed's, prefer to keep breed by breed

Tiny hens and large roosters are a bad combination. The big rooster will probably claim the banty hens as his own and the banty roo will still be lonely.
The banty will still lay the same size egg regardless of who mates her.
