It all depends on the personalities in your flock. My large fowl and smalls get along, but my flock is very docile and laid back. My standard rooster is huge and he doesn't care about the bantam girls, nor does he bother with the roosters. I'm not certain he even considers them the same species...
I hope you get 100% hatch. I'm looking forward to seeing the lemon cuckoos. Porcelain is the same as blue cream in silkies. It's isabel in orpingtons or brahmas. I didn't realize that anyone had bred crele silkies. Those should all be really interesting.
It's not so much the color genetics that I was referring to. I was thinking that because the silkie feathers are so fine, the color might look completely different? Like the porcelain/Blue Cream silkies color looks so different than isabel orpingtons or brahmas, even though it's the same color...
