I was just told (by a seasoned crestie breeder) that Jagger has "ideal" structure. I really hope a lifespan of 15-20+ years is accurate, because I'd love to give breeding a try at some point. I just don't have the space right now (and he's still a baby, anyway...18-24 months is my best guess, and only 25-26 grams). And I'm a sucker for his red and black spots
