HELP!!!

[WVduckchick]

I'll have to get a better picture of it tomorrow, I don't really know how to describe it.

That baby picture I just reposted, he is the one in the back. You can kind of see the little dip on the side of his head. It was like slicked back fluff then.

It doesn't really stand out now, but from watching them both grow I can definitely see a difference. It's off on one side of his head, not really on top like a crest. I thought it might be from the less than ideal incubation? It just looks...different?

I'll catch him/her tomorrow for better pictures. They are still super friendly (could be that they lived inside for a few weeks hahaha) Maybe y'all can help figure it out. I'm kind of just curious.

Crests come from a gap in the skull, and I've seen all different levels of crests, from huge overflowing ones, to very small ones. I have one crested drake, his is fairly small. Do you know if any cresting could be in their background?
