Hello, a few months ago I got some ball pythons who are strict live feeders. That is when I started getting in live rats, the last time I got a group of rats I noticed to late it was a nice mix of males and females. This resulted in ending up with 2 females which are pregnant now, hold them back instead of feeding them off. They should be laying soon and they already are making a nest, now after some looking around and reading I wanted some clear answers on some clear questions I have!

I am breeding them for feeder rats, but I must admit I also like going for combinations and see what kind of pups come out! Are there any lethal combinations?

Since most of my ball pythons are feeding on frozen thawed and I have no intention of switching them to live, what is a good way to prepare them to go into the freezer (the excess)?

What do I need to look out for while picking my breeding stock ? (diseases etc.etc.)

Can I house multiple pregnant females together? If so what is the recommended size of this group and pro/cons ?

How big (in cm if possible ) should the tub be for 1 female or a group of females ?

Hopefully I can get some answers here
