I want to get a colony of dubias started, and I have finally found a source (hopefully). I want to know what exactly I want before I place the order.

Currently, we have a spiderling of G. rosea eating about a dozen 10day pinhead crix a week, but we would also like to starting giving bugs to our crested, who would probably eat large 10day pins, maybe smalls at the moment.

The main reasons for the colony are....
1) We want to get a beardie and/or chameleon this summer.
2) We do not have a car, and it is a pain to go to the 1 petstore in town that carries the size of crix we need. I realize it will be a while before we get to avoid this, but the sooner the better.

With that said, what size of colony do you all think we should start out with? Be as specific as you can, especially with whether you think just breeding adults or a mixture would be best.
