I am as much a beardie lover as I am a rodent lover, and I feed rodents to my snakes. So I am not here to preach about which animals should or should not be feeders (I feel all animals are equals anyways)
However, I think your approach is very strange, to say the least. I mean, who goes about aquiring a new pet because they have an abundance of food on hand?
"Dog food is on sale so I stocked up, and bought a St. Bernard while I was at it!"
"My mice are producing like crazy! Why separate them when I can get 5 more snakes to eat the excess?!"
"Our cattle and chickens are producing more than ever this year... what better reason to have a baby?!"
Keep in mind that a new pet - even a snake - is a very serious commitment. I hardly think having some extra "prey" animals on hand is reason enough to aquire a new pet.
JMO.
The point I am getting at is that you shouldn't breed more creatures than you actually NEED. If you aren't selling as many beardies as they are producing, then why not destroy your eggs, or (better for your female) separate them by sex? If you plan to breed bearded dragons as feeders, then so-be-it. But I would warn you that they are probably not the best thing for any animals' staple diet.
Beardies are so common now that there is little need to create more hatchlings. I would urge you to think with some logic for the wellbeing of these animals.
