I am on day 10 in the bator for Crevecoeur eggs. One of the cuckoo Marans roos is the father! I can't imagine what these chicks will look like. One egg is from a non-bearded Crevecoeur and the other eggs are from a bearded one. The Marans is a feather legged one. Any guess what coloring they will be? What do you get when you cross a black bird and a cuckoo one? Cuckoo Crevecoeurs would be pretty cool.
