Hello everyone! I've got three chicks that I am raising for a neighbor, but I need some help interpreting the genders. They're 4 weeks old. Here are the culprits:
Suspected cockerel #1. Some pink coming in on the comb, but not quite as much white as I'd expect (his color is between the other two chicks). Thick legs. Very dominant and has even mounted another chick. Little stinker.

Suspected cockerel #2. Lots of white, but a very pale comb. Thick legs, as well. Has started squaring off with SC #1.

Suspected pullet. Lots of black, pale comb, non-aggressive. Also, she doesn't have a single comb, like the other two
I know that's not an indicator of gender, but I thought it was interesting.
