welcome to BYC!
They look like roosters a bit, but I cannot tell. I think we need a better pic of the comb and face.
At feed stores sometimes if people are always handling the chicks the bins get mixed up.
I am glad you joined us! Like @redsoxs , I am not to great at guessing genders either. But he gave you a great link to explore! I hope you enjoy yourself here! Best wishes!
These are golden comets? If so, which they look like, my guess is that they would be roosters if they all look like this. If I'm not mistaken the hens are tan and red ish where the boys are white and tan. But then again, I am still new to this too... search for a thread on sex linked Golden Comets.
