I don't keep track of what I've spent. I have a good idea but not exact totals. This year was my first year producing. Out of 3 clutches of eggs I produced around 4.5-5K in hatchlings at average market value. I'm only keeping back 2 females from the 26 eggs my girls produced. I am no where near paying off my intial and on going investments. Is that dissapointing? No way! I don't like people saying you can or cannot make money doing this. It will all come down the individual breeders dedication and wise investments or un-wise investments.
I love breeding, but it's not for everyone. That will be up to you to decide.
