They look like they have a straight comb but it got me to thinking which breeds start out dark and feather in white..... Cackle does have White Jersey Giants and they have straight combs.

Where did you get them? If a hatchery - which one (it helps if we know the hatchery so that we can see what they offer)
Best guesses on a few:
2 & 3 cochins
11 look like they have tops hats - Polish if they have 4 toes
