I am brand new to chickens. My first little "flock" only has 3 chicks that are 6 weeks old. 2 are a bit larger than the 3rd. I suspect one might be a rooster because of the way it acts. Dominant and does chest butts with the others. But I have no idea. Here are some pics. I bought them at Tractor Supply Store. They were all supposed to be females.
