Rooster or Hen?

[wrightsflock]

Hello everyone, I am new to the site and very anxious to read all the information everyone had posted. Also, I would love for someone to tell me if I have a rooster or a hen. These precious Barred Rocks joined our family the Friday before Easter. We purchased them from TSC. They thought maybe they were approx 1 week old. I'll post both old and new pictures. Any guesses? Thanks in advance!
This picture is from the first couple of weeks that we got them.

These next ones are from today. I'm thinking this one may be a rooster?

This is the other barred rock. I am thinking this one is a hen.

So any ideas????

Welcome to BYC!

They both look like pullets from far away (neither has extremely large and/or red combs), but a closer picture may help.

Beautiful chicks anyhow!

Thanks, yes the combs are not very big but the first one is turning red unlike the second one is still yellow. We also got four "pullets" but I don't know the breed. Any clue??
