It would seem lots of people should confront this question before they go down the breeding trail.
There is considerable time and money that goes into breeding any dragons whether it's 2 or 10 dragons.
The market is definitely shifting away from normal dull colored dragons to the high end morphs, and most pet stores look at local breeder sales as a rescue. That is "rescue"you from feeding the monsters until you go broke, lol.
IMHO, Unless you go all in and put down some cash on some GRADE A breeders you are lucky to make your investment back over the course of a breeding season, and even with "collector quality" dragons there's a lot that can go wrong. It can become easy to see prices/clutch sizes/multiple clutches and do the math to make you RICH, but feeders, electric bill, cages, good dragons, and time spent managing everything is a harsh reality.
I heard someone post on a different forum that you are better off working at WalMart if you want to make money. At least you get paid, and can get some supplies and your own food cheap while enjoying your dragon.
All that being said, we enjoy collecting AWESOME bearded dragons, and breeding allows us to upgrade our collection and teach my 3 kids about reptile reproduction and growth (home schooled). I have a good business that pays great, the only reason I breed is to pay for a hobby I love. It's kind of like gardening for me.
