I am wanting to create a dark brown egg layer that has either a pea or rose comb for frost bite prevention in the north. My Marans boys get nailed every winter. It would take a few generations of crossing back to Marans or Wellies to get the egg color darkened again but I have time. I just can't decide what breed to use for the comb donor. I would hope to end up with a bird that differs in coloration from Wellies or standard Marans coloration, Maybe crele, white, or another distinctive pattern. I already have Welsummers, Blue and Black Coppers, and gold and silver cuckoo Marans. I have a few ideas for the comb donor but I wanted to see if anyone else had a better idea. Foraging ability and a meaty carcass also are good things for us.
