Yeah, I think some breeders just don't feed them up as fast if they have a lot of snakes, or if they're planning on selling them anyway. But she's been hogging out since I got her on f/t, and she's put on 300 grams, so I'm not real worried about it.
She's also the gymnast of the the bunch, always has to be in the highest spot possible, and she never falls. Very muscular and agile! My 900 gram 2008s are lazy and fat.
