The only thing I thought that may be too much is putting 1 male with 5 females. I've just read that you can safely do 1.4 to 1.7

It's not a question of being able to take care of them, or there not being enough space. The bins are sufficiently big enough. And I've had plenty of experience caring for rats. As for producing unspeakable amounts of pups, I eventually need no less than 200 a week just to support me and my buddy's snakes. From what I understand, my initial numbers won't produce that much, or am I wrong?

My plans are to remove the pregnant females as they become pregnant, and put them in another bin until the pups are weaned. So the mother wouldn't even have the possibility of becoming pregnant again for at least 3 - 5 weeks from what I understand. Then just start the process over.
