Educate me please!

I just discovered one of my EE hens is a roo. He'll be my first rooster. I think we'll keep him because my flock could use a rooster and I like the idea of being self sustainable.

He's an Ameraucana/EE, so he's likely to have the blue egg gene which is very exciting to me. As I understand it, if I breed him with my cream egg layer we should theoretically get light blue eggs, and if I breed him with one if my brown egg layers we could get green.

Can anybody tell me if my understanding is wrong, missing information, etc..

If he is homozygous for the blue egg Shell mutation. You never know with EEs

So, regardless, he might still have green, or brown genes?

One their is no green egg gene. Green eggs come from the blue pigment coating a brown egg. Homozygous would mean that both of his genes are blue egg. If he was not homozygous then he would have to be crossed with another blue-green egg layer to get colored eggs.

I know someone can explain this way better than I can, but. Eggs are either blue or white. Brown eggs are white with a brown layer 'spray painted' on. Green eggs would be a blue egg with the brown 'paint'. Your EE could carry one, two or no blue shell genes and may or may not carry the brown layer. Blue is dominate, so it only takes one copy to show. But being a mixed breed male you can't know what he carries.

Ok. Good to know.
I have an EE/ameracauna cockerel I picked up by mistake this last week.
Current flock:
3 barnevelder hens
1 SLW hen
1 farmyard mix, was told she's a SLW and she's very obviously not and has green legs and lays creamy, almost pink eggs. She's actually my favorite, great temperament, hilarious, and just an all around joy. Even started hopping on my shoulders one day, which I decided to discourage.

I just adpoted a barred rock and some beautiful golden bird which I think is also a barnyard mix. I haven't seen their eggs yet as I've only had them a week and I think they're still stressed.

This is right on.
He is going to have two blue shell genes, two non blue (white) shell genes or one of each.
He will pass on one of his genes so if he carries two blue he will pass on a blue. If he carries no blue he won't pass a blue one. If he carries one of each he has a 50/50 chance of passing on a blue.
The brown which makes green on a blue shell egg is a whole different set of genes. Its said there are at least 13 different genes responsible so depending which genes if any they get will determine how dark of green the eggs turn out if a blue gene is also present.

I know the people I adopted him from had a hen laying green eggs so perhaps he's got the gene
