After having read thid thread I can say that most suggestions are close to the mark. Some hit the nail on the head like Odie eho breeds rodents proffetionally. Some comment I thought where a little vague but you get the gist. Hope all works out for your rats. I have my rats breeding. I use many of the pinkies to feed to my hatchlings or blue tongues. I use fuzzies to small rats for the juvies and other small snakes. I try and make sure I save a couple of rats per litter for my adult female olive python that only seems to want rats at the moment. I have founf some guy that sells jumbo sized rats for $3, I bought 20 from him so I could concentrate my efforts on my smaller snakes and not worry so much about being food for the afdult snakes. My olive python fills up on two jumbo sixed rats. I had all my rats in an aviary where they had so much more space but became less reproductive so I went back to the lab tubs. Try different techniques with your rats. Experiment and see what works best for you. There are rat pelleta you can buy that have everything the rats need. They are found in pet produces stores. They are good. Still treat your rats with bread, vegetable every so often. Hope this helps.
