Accidental Rooster?

[ninafe]

Hello! I’ve got four 6/7 week old sex links/ISA browns - whichever they are called The sticker at Tractor Supply says they were pullets bred between RIW and RIR. Lately I’ve noticed that this particular chick has a bigger comb and less brown than the other chicks. What do you think? A rooster?

Pullet. They are sex-linked. Males would be white.
