I run at least a 3:1 ratio.

In the breeder tubs I have roughly 600 females to 200 males.

I only feed 2 dragons, the rest get sold off on craigslist and I donate to the humain society and herp society also.

I have been breeding them since Jan of 2012. I started with 500 mixed nymphs, 50 adult females and 10 adult males. I did not feed out of the colony for 3 months. Now I could keep the local petco in feeders every month!

One thing I never mentioned, temps. You need to be between 85-95 for best breeding. I set at 91 so if it fluctuates a little in either direction its ok.
