I plan on starting a dubia roach colony for my 1 year old male Bearded Dragon. I'm just not sure how to set up the bin and everything. I'm plan on getting a big Rubbermaid bin with a screen on the lid. How many roaches should I buy to start my colony?How long will it take until I am able to start feeding out of the colony? How should I heat the colony? Where should I buy the Dubia roaches from?Please feel free to tell me your setups.
