12ish week old Cochin Genders and colors?

[Mariella posey]

Well, I'm pretty sure I have 5 Roos and 14-15 Pullets but I would love some input on these cuties! Also what colors are they? I've never focused on color names before so I'm still really new to it! Sorry they are all muddy, their pen flooded in yesterday's rain and I had to scrap it and start over with new bedding.
I will post the ones I think are Roos first.

All cockerels if 12 weeks old for the boys, but I think some of your girls are boys; the blacks with red/larger combs and wattles. Are these bantam cochin? Pullets would not have such combs/wattles at three months of age.

They are all LF Cochins. Any ideas about what colors I have? The Buffs have black freckles on their wing feathers and some of them have grey downy feathers? The blacks have some white spots on their wing feathers, And one of the Bard is darker.

Sorry, I'm not good with color names. Are some silkied cochin? In the pictures some of the blacks look silkied.
