Ameraucana help, please!

[hessclan6]

I have a Lavender Ameraucana roo that I got as a young chick and have been growing out specifically to use with my mixed flock of girls for creating Easter Egger chicks. I've done three small batches of chicks so far and ALL of the chicks have been either Blue or Black. I thought that the mother's would have some influence on chick color but so far, not at all. Explain this?

What color is the dam? She still may be influencing the hatch just through a recessive gene one you cannot see as a genotype.

There's some information about lavender's here/: https://www.backyardchickens.com/a/basic-chicken-color-genetics

Most of the hens are Easter Eggers. Here he is with some of the girls in question. I expected black from some of them (Australorp) but not with the other colors.
