There is the chance they could be gravid if they were paired with males, that's why it is important to get husbandry right now!

You want to separate all of your snakes, they aren't social animals. If you like them being in displayed cages, you should think about building a nice wooden enclosure with a glass front--you can see them, but it will be easier to keep in humidity and heat. For now with the tanks, use a piece of wood or aluminum foil and cover most of the top(leaving a hole for the lamp) and spray to keep up humidity.

Make sure you have readings on the heat and humidity in your cages! Guessing is dangerous, so that is an important thing to buy

and stick to a regular weekly feeding schedule. One prey item that is as wide as the widest point on the ball python once a week. Unfortunately there is a lot of misinformation out there(A pet store told me to feed my ball python once every 6 months, a regular adult mouse...Another one told me she'd do fine eating hotdogs. Both were 'reptile specialists') so what is important is to learn what is right..

This website has a nice caresheet on ball pythons, I would read that and make sure everything matches up. Make sure each snake gets at least two hides(get identical hides, snakes will choose the hide they feel safest in..that means if they have a hide they don't feel as safe in, they won't go to it, even if they need to be on that side of the enclosure!)

Good luck! You have a lot of work ahead of you! But I'm sure you can do it!
