Try to find a true Ameraucana breeder or use Crested Cream Legbars for the blue genes. Most CCLs and True from a breeder Ameraucana have double blue egg shell genes.Thank you very much for the explanation Ron. I was really hoping that at least a portion of their offspring would lay blue/green. Fascinating stuff... I'll cull and replace these two girls in the near future.
Cheers,
