everybody has different favorites, so trying to figure out what everybody's favorite morph is, is a bit difficult. On a sellers point, the new things seem to be translucents and hypos. Strong reds are always good too.
It doesn't matter which clutch the babies come from, it is still inbreeding to breed two dragons who share the same parents. The genetics don't change just because the dragons are from different clutches of the same parents, they are still technically brother and sister..just different ages. If the father was different or the mother different...then the babies are not as closely related, be half brother/sister.
If you are hoping to breed, it is best to get dragons that are as unrelated as possible. Buy from different breeders, check to make sure you know where they bought their stock from so you are not buying cousins etc.
Another point, breeding dragons can be very costly and alot of work. Do it because you love keeping dragons, not to make money. While it is possible to make money, it is not guaranteed. The first couple years will be the most costly, as you buy everything you need and you will spend alot of money on food, easily as much as $25 a day on crickets alone, once you have a couple clutches of hatchlings running around. You need space to house all the babies, a good method of advertising and arrangements for shipping, websites help too. Or the ability to go to shows as well, to sell off all your offspring. Thinking of just selling all your babies to a pet store isn't the way to go. Many pet stores won't buy babies from local breeders, some already have suppliers are may not be willing to try new ones etc. Research your market completely, before getting into breeding. Remember bearded dragons are prolific, capable of having up to 100 babies a season easily. (average may be more like 50-80 but big healthy females can lay clutches as large as 25-35 and as many as 4-5 clutches, some will even have 6 or 7 clutches)
