What gives that away? (Trying to learn)

I am unsure about the lighter oneS but the darker one... I lean roo. The comb is much redder. He has very little tail.
There are three chicks in total, correct..?
One of the lighter ones doesn't scream roo to me. She has a smaller comb, a fuller tail, and more delicate feet.
The other looks like it could go either way.
This is the one that looks most girly to me.

Yeah, sorry, I see 3 cockerels. They all have red combs and at 6 weeks pullets don't have red combs. Plus the flashy patterns on the 2 brown ones is more common in boys.
