Ryan , 3-4 years would be a good age to look at breeding them , but as others have said there is a lot more work you will need to do than just chucking them in a cage , conditioning , cooling etc then you will need to house the hatchlings , sell them , get them feeding etc .
Keeping and Breeding Australian Pythons is a great book with stack of info on most commonly kept pythons.
