Do you plan to keep the babies or sell them, and to who? Also females are known to store sperm so if you do breed them you need to be ready for a full season of eggs and all the babies, not just a few.
You won't be able to house them together due to the size differences, so you'll need at least 8 new cages. Plus all the hides and water dishes and food and heat, well you get the idea. Also don't forget babies eat lots of small food items everyday, so you'll need at least a few hundred crickets a week, plus the stuff to gutload them.
Bottom line...make sure you know what you are going to do with the little ones, and exactly what you are getting yourself into.
