-When they're on single pinks (2-3g), I feed every 3-4 days. (Snake = 4-15g)
-Double pinks (3g x 2) every 4 days. (Snake = 16-23g)
-Small fuzzies (5-7g) every 5 days. (Snake = 24-30g)
-Regular fuzzies (7-9g) every 5-6 days (Snake = 30-50g)
-Hoppers (9-12g) every 5-6 days (Snake = 51-90g)
-Weaned (14-20g) every 5-7 days (Snake = 91-170g)
-Adult (24-30g) every 7-x days (Snake = 170+)
This is by no means scientific, and not all corns will cooperate 100% with the schedule. The weight ranges I gave for the prey and snakes are approximate. I'm very consistent in my feedings. Some people feed every Saturday, for example. If they get a refusal, the snake has to wait for the next Saturday to get another shot. I don't do this. If a snake refuses today, he'll get another shot in two days.
I used to drag all prey items' back ends through a supplement mix before every feeding. I've cut it back to every 5-6 feedings. The mix is a 2:2:1 ratio of Rep-Cal Herptivite (vitamin/mineral/amino), Tetra-Fauna ReptoCal (calcium + vit D), and Nutri-Bac (probiotic).
But I also give a lot of credit for my results to The Mouse Factory. I think they put out a superior product. The importance of the nutritional value of the prey items can't be emphasized enough.
Good luck! I hope this info proves to be useful.
