Jean, I have a white rooster that I hatched from one of your eggs last fall and can say with confidence that he at least doesn\'t carry dominant white. I hatched about 80 of his chicks this summer and the only white chicks are the three that I got from my white hen (also one of yours) before she died. His babies from my EE (BSL cross) hens are all colours of the rainbow (no barring though). Crossed with my buff Ameraucana hen he produces varying shades of mostly-buff babies with blue leakage; crossed with BBS Ameraucanas he produces straight blacks, blacks with silver or gold in their hackles, and blues with buff leakage.
That white hen was a big nice looking girl, she laid by far the biggest egg of all my Ameraucanas, and she had a wonderful friendly personality.
