Crossing breeds

[wccs2001]

So I have a random assortment of backyard chickens. My roo is a buff Cochin bantam. There are four standard hens. An EE, a cuckoo marans, and two white Sussex. I've noticed the roo doing his business with all the hens, but figured with the size difference, the eggs would be infertile. About a month ago, one of the Sussex went broody on a handful of eggs. I decided to let her run the course and in a month just throw the eggs out. A week or two into it I candled the 5 eggs she was on. Two EE, two Sussex and a marans. Much to my surprise the EEs and the marans had chicks inside. Today they hatched. The marans chick pecked a hole and died without ever emerging. Both EEs came out and are doing fine. I'm wondering, if my Cochin bantam roo has bred with my EE standard hen, what sort of chicks do I have.

They are both buff colored, the size of standard chicks, feathered legs. One has a small dark brown spot on the back of its head. Will they carry a blue eggs gene?

they are still ee's

size doesnt matter as long as the right stuff connects to fertilize the hen, at lest its a bantam roo to standered hens instead of the other way around. they will still carry the blue egg gene but what color the eggs may be is unknown until they lay (i think it will still be blue)

if they have pea combs (it will look flat right now), it is likely they will lay green eggs. Cochins lay brown eggs, so the brown will coat the blue on the egg and look green. If they have single combs, they will lay brown eggs.

Interesting. Thank you very much!
