For starters stick to one species first. Also if you are going to breed a number of animals you need to understand the market for those animals. Burms are gonna be hard considering you cannot ship out of state anymore so what would you do with a bunch of hard to sell babies not to mention a dying market. Also it is very expensive. Colubrids are a funny bunch. If your breeding for money you have to produce mass quantities to make anything off of corns.
