Depends on how big they are in a 12 x 9 x 6 box you can fit young 3 hatchlings.

If they are 200/250 grams I only recommend 2 for a 12 x 9 x 6 box

I recommend you buy your supply bulk rather than buy kits.

Adults that are 1500/1700 grams I use 11 x 11 x 7 box, if they are bigger than that I use 16 x 12 x 8 boxes
