I thought they were nasty at first and I was NOT into them for a long time but I really couldn't say anything better about them now that I have them. They don't jump, chirp, smell, or any of the things that make crickets a pain. They are EXTREMELY simple to keep and breed and you won't even know they're there. They have the best nutritional balance of any of the insects and you only have to feed 4-5 of them versus 30+ like crickets to a beardie.
Seriously, the longer you wait to start breeding these things the more you're going to kick yourself later. I've saved hundreds of dollars at this point. I throw them a scoop of the rat food and a scoop of water crystals twice a week and keep the tub behind the mini fridge where it's warm. That's it. I clean it once every 3 months. Yes, once every 3 months.
OP: congrats on the colony. My best advice is keep them warm (80-90) and don't feed out of it for 2-3 months. The females take probably 6 months from nymph to adult but then they live for a very long time as breeders. They also seem to breed better when they're very crowded, so wait till the colony is just clusters of them before starting to feed out of it.
EDIT: oh, and they can't climb smooth plastic... so easy to keep
another pro tip is to go to your local grocery store and get the store manager - tell them you are wondering if they have egg cartons kicking around because you want to do crafts with them. My local hannaford gave me a 5 foot sleeve of unused egg cartons that is going to last me years - for free
