Ok so I have 5 snakes now and food is going to start costing me around 60 bucks to feed a month but I foresee myself buying more snakes seeing I'm going to start breeding next season. Now supplies I have come up with:

Drawer rack with ventilation about a 28 qt tub (2 high)
1.3 ratio of males to female rats in each tub
Aspen bedding
Rat food, but I have seen some dog foods work just as well
2 water bottles

I was just going to let them go at it for awhile do get the colony going and to get some babies up to size so I can freeze them at the size I want.

Going to the store to buy the rats and they are about 60-80 grams so small rats and I have heard that I should prob wait a month before breeding them, is this true. Also anything else I should know or get?
