How much does a bearded dragon egg cost?

A bearded dragon egg is worthless. Unless you have incubators set to keep the correct temperatures it may as well be tossed in a garbage. Fact is the egg itself could be infertile and will only rot. Even if you get lucky and have a baby dragon hatch from the egg, until it is about 6 weeks old there is a high chance that unless you keep the conditions perfect it will not survive. That is why breeders will not sell you a dragon under 6 weeks old, too much chance of them dying.
