Thanks for the enlarged photos, really helps! Number 3 and number 5 may end up being male, too early to be certain. Rest look like pullets. Number 1 and number 6 are likely F2, assuming they hatched from a green egg.
Nice looking birds! I suggest reposting when they are around 12 weeks if you are in doubt by then. You should get some nice eggs from these. The ones that hatched from brown eggs are likely F1 (the pea combs) and will lay a nice olive egg like mine does. The F2s may lay a darker olive or a nice dark brown. Sounds like a win-win to me! ☺
