Even animals from the same clutch can have different metabolisms and different feeding frequencies. I have 4 six month old siblings kept under identical conditions. Three of them eat on the same schedule one does not. Current weights at six months 350, 600, 750, 800. My rule is if the animal is hungry and not fat I feed it the proper sized prey item. Some babies I feed twice a week. Some I feed once every two weeks. Totally depends on the animal. Understand however that all but a couple of my animals eventually go off food for a couple months a year because of the way I feed. This is acceptable to me, however it bothers other people because they think something is wrong but it is perfectly natural for this species.
