But a lot would depend on your local pet shops. If you really want to breed rodents then...
FIRST, I would check around and see how the market is. Ask them if they'd be willing to buy a few here and there. My experience is pet shops are always looking for rodents that could be feeders OR pets. Most of the rodent suppliers in my area have black, white and black hooded. Nothing else. My colony has many more colors and I have no trouble selling off my surplus "pretty ones".
Second, get colors!!! Just as easy to breed pretty colored ones as plain ones!! Plus with various colored ones if/when the colony gets larger, it's easier to tell them apart.
