Friendly advice from someone who has put together a bunch of raffles. Don't worry about using your own dragons. If you make a post in flight asking for dragon prize donations, plenty of people will offer dragons. Just make sure that you list specific criteria or you are going to get deluged with dragons that no one will want to win in a raffle. You'll want to ask for things like level 25's, gen 1's with matching colors, older dragons. No offspring. (Genes on gen 1's do not matter, most people will want to gene themselves.)
