crestie's age?

i just bought a crestie on tuesday. i weighed it and its only 7 grams i was wondering about how old it may be its only about 4 inches long maybe a bit more. i asked the guy at the pet shop i got it from but he was just there for a friend he didnt have a clue when they hatched does anyone know roughly how old it might be a month or soo maybe just wondering.

at 7 grams it is probably somewhere around 4 months old. if you look at this thread: http://www.ball-pythons.net/forums/s...ad.php?t=26873 there are some photos of cresteds of different ages on a ruler to show approximate lengths at certain ages.
