BCM juvenile chick questions...what is normal?

I was wondering, is it normal for a BCM chick to have green eyes and what appears to be a rose comb? The hens and rooster are both very much BCM (Dan's line) and no other rooster was in with the hens. My husband tells me to wait it out because anything other does not make sense, but it is getting to me already, like an itch that won't go away. Also, a black pullet appears to have almost a silkie-looking tuft on the top of her head...is that normal?

Is your feed GMO? Because those features are not normal. 

I don't think so. The fellow (seed grower) that we get the feed from hates GMO and sprays very minimally (we have a distinct dislike as well), but you never know. It makes me wonder if it is from what is in the water...ugh. I would post a "lol," but this whole thing bugs me too much at the moment...itchy, itchy!!!

I am hoping things change as the chicks grow, but I don't know...

How old are they and if you post photos we may be able to help better.
