Does anybody breed fancy rats and use them for feeders?

I want to start breeding rats but I want to breed them as a hobby along with being food for my snake. I will be selling the fancy rats to try to compensate for the cost of maintenance and maybe even a little extra for profit.

1) Would I be stupid to feed fancy rats to my snakes instead of trying to sell them?

2) Would I be better off just breeding breeder-specific rats such as regular hooded rats for my snakes and keeping a separate tub or two for my fancy's?

I was thinking I might as well just breed fancy's and then take a couple out each week for my snake. She currently eats 2 smells a week. I will also be euthanising and freezing them and it seems a little stupid for me to freeze a rat that could potentially sell for 20-30 bucks. I'm probably going to have have a couple fancy tubs and a couple feeder tubs but I was just wondering what people on here thought/did.

Thanks in advance,
