breeding balls may or may not be a good idea depending on your plans. assuming you plan on selling the offspring, can you home the ones that do not sell?
a better idea is to build your collection, and think about the breeding part later on. after you have an understanding of the efforts and expenses involved in keeping a number of snakes. snake keeping is not about how many you have but about how many you can sustain. at first i dreamed of having a really large collection, but after keeping some for a while, there came a time when i reached a threshold that my hobby is becoming a lot like work due to the number of animals, and the expenses is hurting my finances, so i had to stop. if i want a new morph, i give up one of my exisiting snakes in order to maintain that comfortable level at which i can enjoy. this is my first year trying to breed balls, if i'm successful i will sell, if nobody buys i have a ton of friends and relatives that want pet snakes.....
