Not only is this a concern, but there are some questions to consider with this as well. Do you have the time of day to check over each day every cham to make sure he/she is safe and healthy.? Do you have the money to pay for any vet bills that will come up if more then one cham gets hurt.? Do you have the money and time to care for each baby that might hatch, whenever they hatch.? Since your looking at them always being together this could happen whenever. Each baby will need its own cage and what not until its of age to be sold. Are you really prepared for what you are asking for right now.?
Just some things to think of.
As of now this is all i do. All my time is put into care and building new enclosures. That and go on many herping expeditions around the state. But only when i have the time to spare. This is by no means a way to become rich. The babies will more than likely only be sold for 10 bucks each since they will be going to a wholesaler. The ball pythons is where the money comes in, this is just another side hobby.
On each baby having its own cage. I have personally never seen anyone do this. But a 1.5x2.5 by 4ft tall cage will be more than enough room for a few 2-3 month old babies.
