Responsible breeders don't breed for profit, they breed to improve the breed.

Only back yard breeders can make a profit as they cut so many corners when it comes to breeding.

Here is some research I have pulled together to write a couple of articles. Although it refers to breeding cats many points also apply to breeding rabbits.

PS. Only back yard breeders would consider selling babies (rabbits, kittens or puppies) to be sold via a petshop to anyone without considering whether or not they will be good forever homes.
