Where do your animals come from, if I am not mistaken a petstore.
So, if that is the case, the answer is no you should not.
The reason being you have no idea of where they come from, if there parents have health issues that can be genetically transmitted and the only way to really know is with pedigrees and good responsible breeders. Even if you have great homes for the kits, are you comfortable at giving or selling animals to potentionally good homes that may have to dish out hundreds of dollars at the vet because the kits have genetically transmitted health problems. Following that what will be their opinion of you selling such.
Granted kits are cute, BUT an other reason not to would be to possible put the lives of the mom and kits at risk for many different reasons, therefore costing YOU more than 129$ of vet bills, more like hundreds and possibily thousands and no kits for good homes.
If making money was far in the back of your mind, you don't make money breeding unless you have hundreds/thousands of chins and even then I'm not sure.
Take the time to read the breeding section and see the horride things that may go wrong during and after pregnancy.
I don't think it is worth playing the RUSSIAN ROULETTE with animals of any kind. If you care and love your chins then you know what to do.
Hope you make a responsable choice
