Hi,
I'm in WA and breed true Wheaten & Blue Wheaten Ameraucanas and Welsummers. I also show them.
You can see my birds on my website. Just click on the applicable album for the breed you want to see.
You will notice that I have/had Easter Eggers. I just have the one left that I am breeding to my two Wheaten and two Blue Wheaten males but her eggs are purplish, they can't be confused with my blue eggs from the Ameraucanas, and besides that I separate out all my birds and take great care to know exactly who I'm breeding as well as keeping good records.
Hope that helps. Just let me know if you'd like some eggs or chicks.
God Bless,
