Some people will have trouble and some wont. There are many variables that effect the ability to sell your snakes such as reputation, quality, presentation, qualities of the owner, ect. For instance, I have had several clutches recently and have only been able to sell 2/3 of them even though they are pretty nice representations of the morph, priced accordingly, I have multiple positive feedback, I take care in selectively breeding, and my snakes are essentially the same snakes you would get from a bigger more well known breeder (for instance, I purchased my fires directly from Constrictors unlimited, my yellowbellies from BHB, and so on). However, people are much more likely to purchase these morphs from them because of their name, presentation, and reputation. It is the combination of factors that will help you to move your snakes. On the other hand just make sure you have the room and resources to care for many hatchlings just incase. Even the best looking examples of morphs can produce some ugly ducklings that nobody may be interested in. Its all about knowing how to market what you are selling and letting people know why they should purchase from you.
