I personally wouldn't buy a BP feeding on anything unusual. I prefer to get them eating rats, but if it's nice, maybe if it's feeding on mice. Chicks? Never. Quail chicks, especially never.
Another thing I don't see mentioned is to try to gauge the price drop that might be expected from some morphs. If you have a codom snake, the price mark may drop each year as more of that codom enter the market. So you might raise a baby up but then it's still worth the same price even as breeding size animal because the price dropped the next year.
Also, males tend to be lower priced, as many breeders will sell off unneeded males as they make and hold back combos, while female breeders are more desirable and able to make offspring.
It might be a better business plan to sell males and the lower priced codoms off younger, and hold back recessives, combo gene animals and females to sell at a larger size.
