There are only two birds, they are the same two in each picture. I am unfamiliar with the term pullets, is it your opinion that they are both female?

No, these two were hand selected and two "females" were chosen

We suspect one of our chickens may actually be a rooster, please advise?

More precisely, we are noticing a more pronounced crown and gill but those are the only defining features thus far as the breed makes it difficult to discern feather length, etc.
