Thanks! I was thinking that the one in the back was a roo and the one up front was a pullet tooI'd say the white in the back is a rooster and the white in the front is a pullet. You can tell by the size of their combs. He might be too young, but the rooster will eventually grow hackle feathers. Hackle feathers are extra long feathers that cover the back of the head and neck. Only roosters have them. Mine are 5 months old, and you can clearly see the hackles. The white pullet reminds me of my Piper...Piper is the yellow silkie in my profile picture.
