Ameraucanas lay blue eggs. The recognized colors are Wheaten, Blue Wheaten, Brown Red, Silver, White, Black and Blue
Any other plumage or egg color other than those recognized is not an Ameraucana, but an
Easter Egger. If the goal is egg production, then Easter Eggers are the way to go. They're much easier to find, and the more economical choice- as you'll likely pay more than double for birds from a legitimate breeder. They are extremely reliable layers, and from my experience, well mannered as well
Hope that helped!
