Hen or Rooster?

[CharityB]

I’m concerned that one of my chicks is showing signs of being a rooster. I have two Columbian Rock chicks that are about 3 1/2 weeks old and one has some pink tones around her comb...I have included pictures and am interested in people’s opinions. TIA
The two pictures of one perched on the green has a smaller yellow comb but larger legs and is bigger overall and the rest are the one I’m concerned is a roo...

Your top first bird has a high likelihood of being male.

Some Rock females are very precocious and develop combs early that are worrisome. But, it should stay yellow and no wattles grow until point of lay.

This appears to be pink and early roo growth.

Sorry.
