The white line came from a flock of Marans that were bred in Michigan. A trio was sent to me and I started breeding them. The bird was small and the egg was terrible.
At first I crossed them with the cuckoo and got males that had a sort of ghost barring to them. After a while I bred them to black coppers because the egg color was much better.
Recently I was kindly given a white sport male from a black copper and am presently breeding him to my other white line in the hope of increasing the egg color. I have found that the birds with light colored feathering produce eggs that aren't as dark as those with a darker feather. At present there is no known genetic reason for this.
I'll continue breeding this line until I get a darker egg than the number four being laid at the moment.
