interested in breeding.....
i always believe that the BEST and surely the first step you should take is to make sure you can get rid of them, aka sell them, if you don't plan on keeping them that is. Go to area pet stores. Its better to go to them than to call. Because you don't want to sell them so some shisty pet store that'll mistreat them.
Then, if you can do such, go to some search engine like google and type in "breeding bearded dragons" and read all the information you can. most people are saying the same things, and some people have no clue what they're doing. But, it'll give you a wide spectrum of hints and tips.
beware though...there are thousands of people breeding dragons. soon competition amoungst breeders will get so intense that it will be hard to get rid of normal phase dragons. it all depends on the supply and demand in your area.
hope this doesn't push you away from the joys of breeding but honestly, it can get pretty labor intensive and stressful if you can't sell the 40 dragons you have.
