Frazzles are chickens with two copies of the frizzle gene, which makes feathers curl away from a chicken's body. Regular frizzles have one copy of the frizzle gene and the frizzling is less extreme.
Yes, wait a bit as @JacinLarkwell has stated. I think they're likely frazzles but it's a close call and you should be able to tell later by brittleness of the feathers.
