Okay I am just about 90% sure this is a roo. He's a 5 week old SLW, and as you can see the comb is pretty red, and there are three distinct rows. BUT I was looking at the feathers coming in on his back and neck, and they are not the white color that the Roos have, they look more like the pullet feathers. But I'm not sure so I will let you guys give input! Thank you!
