Remember that does not matter whether it's a hobby that pay for itself or a business making an extra income or allowing to live from it, the tought process before engaging into this venture is to ask yourself the right questions.(This will also be just a hobbyist breeder, will not be a business at the start but if it does indeed progress then I might think about it )
Am I ready?
How the animal I plan on pairing worth pairing or am I just add to a flooded market (when it comes to certain mutations) and be stuck with the animal I produce?
Do you have sufficient found if breeding lands one of your animals to the vet for surgery?
Can you properly house 6 to 12 additional animals?
If stuck with the animal you produce do you have the means to care for them for 3, 6 , 12 months or longer.
Do you have a reliable source of live feeder? Will you breed your own?
How well do you know the market, do you know where you will sell your animals? Do you know if those animals are thoughts for?
The reason I am mentioning that is a lot of people jump head first without thinking much about everything involved and usually 5 years later they call it quit and sell everything.
Breeding is a lot more than putting two animals together, it can be time consuming and heartbreaking not to mention the financial burden if it does not pay for itself.
So there are many things to consider.
