Breeding Rodents

Does anyone know how many breeding rats it would require to feed 3 ball pythons and could anyone help give insight on how to do this? I am currently watching videos on it but any other help is appreciated.

We have a dedicated section to breeding all things feeder. There are subsections for breeding rats, mice, ASF's(African Soft Furs) and also insects.
Here is the link to that section.
