Rainbow Dixie Roosters?!

[Casurf21]

My little ones are 3 weeks old now. Got them at Tractor Supply. Sold as straight run Rainbow Dixie. I have 2 that are starting to spar with each other and are developing combs and waddles and wanted to see if anyone could confirm for me that they are in fact male!

"Delta"

Thank you!!!

Since the combs are that big at such a young age my guess is cockerels.
