I think I read in another thread (I've read so many in the past few days) that said you shouldn't hatch eggs that comes from small hen & big rooster, but haven't been able to find any reasoning. Our roo is huge compared to our hens. But logic to me is that the eggs are going to be the same size whether we hatch or not. If we hatch golden comet & maran/langshan, what kinda babies are we going to get? All 3 of the breeds are friendly, docile dual purpose. Our hens are very friendly- the rooster, not so much but that could be just b/c he's a rooster and he's still new to us.
