Vicki, maybe I misunderstood Hen's question? I didn't think she meant breeding the ones with the carnation or the wave? Hen's did you mean breeding the other siblings that had normal combs, or am I way off here? I sure would not breed anything expressing a carnation...OOOOOOOoooooooo NOOOOOOooooo!
Debbi, to save on headaches I would cull all if they were from the same breeders. I bought one dozen wheaten eggs last year off ebay and had two chicks showup with the carnation Comb, I cull the entire hatch. I have never had a Carnation show up on Marans bred here. Your two BC males should be clean also.
