Only if you factor in your time as well. As with most hobbies, the way to make a small fortune is to start with a large one... Yes, there are a few that make it a living. For the majority, it's a hobby, and while we might actually manage to break even at times, most people will spend more on the collection than they will make from it.....Once you make enough to cover the price of the breeding pair/housing it is all profit after that.
