I would imagine so. You can either buy a breeder set up which should come with some adult males and females and some nymphs of different ages or just buy a few hundred nymphs and let them grow. Route one will be a lot faster. Route two will take probably 6 months or longer depending how large of nymphs you start with.
I used to sell adult females for $1-2 each and males i would just throw in a bunch for free as i used to just dispose of them as you dont need many males for a colony as they will fight and just eat food and my beardie didnt like eating large roaches.
