How old are they? They look young still. My roo is about 11 months and still growing. Maybe at 18 months he will be as big as he will get.Just picked these guys up yesterday! My new Plymouth Rock flockThree barred pullets and two blue with dark lacing, and of course the roo. The blues aren't completely integrated yet so I have to keep an eye on them, but hopefully they will be ok. You can't really tell in the pics but the roo is humongous!
