The black chicks are probably Cuckoo Marans



Maybe some hatchery quality Speckled Sussex

Could you get pictures of each individual chicken in brighter lighting?

I ordered 15 chicks at the beginning of july( all
Hens, BRs and RIRs) there are 2 chickens (1 RIR and 1 BR) that have large combs, they look like roosters but I was keeping my fingers crossed that they were just growing faster than my other girls... If they have large combs and are bigger than my other girls, should I assume that they are Roos? Ps they are about 3 months old, when would/should they start crowing?

It depends but most roosters will crow at 5 months. The comb size, redness, feather patterns, and saddle feathers can help determine if a chicken is a rooster.

Thank you, these 'mystery chickens' do seem to have different feather patterns, the RIR is starting to get some green and blueish feathers, and the BR is a lighter grey and white vs my pullers black and white coloring

Yeah, Barred Rock roosters tend to be lighter in feathering than pullets and RIR roosters do get shiny greenish blue feathers that drape down on their tails, rooster legs are also thicker than a hen's leg. They do sound like roosters from your description.
