This is a 3 week old Americana chick. I was just checking beaks because I heard cross beak is more likely with them. She is the smallest of the bunch, but I've noticed her beak always has a gap in it.
Can you get a front view or something closer to a front view of the beak? My guess is it's probably showing early stages of crossbeak but hard to tell from just this angle.
I've had two chicks with that gap, and they both did fine. It wasn't a problem for them, like having a cross beak is. Watch and see how it develops. If she has other issues, that's different.
