If you want the best situation for the dragons you will not consider housing a male with females. It would be best if you raised the females together in one large setup and the male in another. A male will raise the stress levels of the females. He will breed the females much to young if they are rasied together and cause them to have growth problems and develop MBD. Its really not in the best intrest of any of the animals. Often males will become breedong crazy and not eat or rest as long as he can see females. He will attack them several times a day and cause major sores on their necks and can even destroy their tails or cause them to loose fingers.
So, if you can't invest in the two tanks for the breeders you are going to have major issues buying the 30 tubs for all your babies! Just think of it as the smallest part of the breedong investment, and one of the most important.
Also, consider hte bearded dragon market is dead. Click on the link and check out my animals. I can't give them away and I have some GREAT colors and they are raised with the best of everything. I just had a sale where I cut the prices that they are listed at not in half and only sold a couple over 2 weeks. And I raise my dragons correctly using silkies, crickets, feeder roaches, greens, pellets and both UVB and natural sunlight. I don't cut corners or have weak or sick stock. I have some of the best in the industry in my opinion and I can't get any business.
Also, if you are breeding females then a few supers and some pellets won't cut it. My females eat around 50 crickets, 20 full grown silkies, and as many feeder roaches as I give them, plus tons of greens and pellets and occasional supers.
Supers are WAY too high in phosphorus fo be feeding many to gravid females. they distort the Calicum: Phos ratio and will lead to the girls getting MBD.
Just some considerations....
Below is one of those dragons I can't get rid of!
