My two Wellsummer twins might be boys!

[Azzerion]

So we recently purchased 4 lovely chicks. We were told all of them were girls, two Isa Browns, and two Wellsummers. The two Wellsummers were a few weeks younger than the Isas, and were a lot more lively, and would size each other up a lot (One of the Isas already established herself as the leader). We are now starting to think they could be boys, due to their behavior. Could anyone tell me their thoughts?
Thing One:

Thing Two:

wellie genders look different aka. Sorry they are guys

 

[donrae]

Boys. We know not due to behavior, but due to color--welsummer hens are colored differently. The size and amount of red in the comb at this age is another sign. You can also see hackle and saddle feathers starting. Sorry.
