ok im getting a beardie

I have decided to go with a bearded dragon as my next pet! I want to start a dubia colony before I get him. Im looking at getting 3 adult pairs and 300 mixed sizes. How long do you figure I will have to wait to feed from the colony? and I was also wondering how easy it is to sort threw the roaches to find the correct size to feed off to a baby? Thanks for any help you guys can give!!

I have no idea about the roaches.....but your life is about to change drastically. You will become a total whupped beardie slave. You will start to tell stories about your beardie...(in his words). You will immed. decide that he needs a larger cage...something along an estate....because of course...he needs to be spoiled. And lets not forget about the early morning veggie chopping. All in all...you will totally totally fall head over heals in love with him. :D
