I'm not Heidi

But I can tell you the trick is numbers and hard culling. Our Basques have a lot of issues from crossing with Pendescanas by the original Canadian importer: mille pattern, white legs, spurs on hens and double spurs on males and smuttiness on hens/black breasts on roos. I also culled for pure white though some folks like those. I started with with 18 eggs from Skyline and 6 chicks from Greenfire and culled hard. In the end I have one decent rooster (Golden Boy) and three "ideal" hens. I added the one dark reddish hen with white legs to improve body color. If you read the Spanish standard, the marraduna is supposed to be a barred red goria, which is basically like New Hamps. My first generation breeders are too "golden" (Blondies) but I'm working on it. I expect it will take several more years to get them where I think they should be.
