I won't even breed like that.  We don't cull for meat here and I'm sure I could even get $10 for those cuckoo roosters whereas I've always given my pet quality and frizzles away free.
I think what I'll do is just hope for a smooth cuckoo rooster, and keep a couple cuckoo hens, one frizzle, the other not, and just let them breed.  Somewhere down the road it sounds like barring dilution can start occurring and I'd have to breed each sex with the applicable solid mate, white, black, or chocolate, then breed them back.  I sure hope I didn't open up a can of worms by getting these.  I just wanted some buffs is how this all started.  
It's fun though and they are so darned gorgeous!
I read in BYC somewhere that cuckoos can be sexed early by comb.  I was wondering why a few of these had tiny red combs and the others are black.  If that is true, then both my little white princess and the NN are roos, as well as one smooth dark cuckoo.  I don't know if I trust that, but I'll be so heartbroken if that white frizzle one is a roo.
