I don't think that makes sense though. In the wild, they breed whenever they feel like it. I'd be willing to bet there's a few out there breeding before they're 3. My amel male is looking for a mate right now. He's nearly four ft. long, but not even 2 yrs. old. No one told him he shouldn't be mating right now, he just wants to! 4 ft. long at less than 2 yrs. old is not small. Most breeders won't breed their females until they are at least 3/4 lb. or 300 grams. My male's almost 500 grams. Unfortunately, my female that's almost the same age as he is, is too small. She's only 174 grams, so she won't be bred (sadly for my male-he really wants her!). I don't believe that's the reason you don't see 8 ft. corns. There are plenty of posters on here with snakes that are 5 ft. or longer. I'm betting my amel will top 5 ft. when he's reached his growth, and I've got a hatchling right now that I suspect will be a pretty big girl when she matures. She's at almost 2 ft. now and she won't be 1 yr. until July. I think there's just large snakes, and one's that aren't so large.
