That's what I'm hoping for! If you know of anyone with very dark egg laying French Silver Cuckoo Marans I would be very interested! Having a very tough time finding some. I'm very picky! Thanks for the help.I'm thinking you're going to get some pretty hens from that cross. I'm a sucker for blue birds, and the Wheaton parent should contribute some interesting color leakage on the neck/chest of the hens. If you have nice dark egg genetics to start with, you should get a nice rich colored olive egg.
