Oh my gosh! He is a beauty! I love JGs! We have a 7 mos old JG roo that just started getting crowing around 6 mos old and his comb and wattles finally are starting to catch up with his giant size. He is still skinny (but tall), and that makes sense since they are slow to mature. He and the JG hens still need to fill out. My JG roo still doesn't have all his hackle, saddle and tail feathers in yet (lots of pin feathers). I wouldn't worry about him not crowing yet. Some of my 7 mos old hens are barely starting to get color in their combs and face and some aren't laying yet. They're just slow.
You're roo looks splash to me, but I am not good at that kinda thing, so my opinions isn't worth squat. He is GORGEOUS though!! That breed is definitely one of my favorites (if not the most favorite!!). I want a blue or splash JG roo someday.
