The problem is some of the pets that are bought at the store, may originally start out as pets, but turn into breeders as those pet keepers want to become hobbiests looking to breed for their first time for "fun". If you are breeding for the experience and not the profit, then Id suggest maybe limiting the offspring in the egg stage by chosing the best few eggs, and eliminating the others. This way you could actually havee only the offspring that you are already guarenteed to pass on to your personal friends you trust not to breed. Also, if this breeding has just recently occured, you can lower the number of eggs she will produce inside her by manipulating her diet at this time.
