No, they are all straight comb. I've learned that rose combs are really difficult to get, even from rose comb parents. My birds from Duane Urch are still a mix of rose and straight, and he has all rose comb breeders. It's just really hard to get. I love my Bama chicks, though. They have the best temperments!
You can tell rose combs right away when they hatch. They look bald in the comb area, lol.
