At some point there is a cost of diminishing returns. With bedding, enclosures, feeders, show cost, traveling cost ect.ect. At some point the animal starts costing you money to produce, now normally this is offset by the higher priced animals in the clutch. If I produce 2 pastels in a clutch of pastel pieds then the pastels are offset by the pied combos. So at some point either some morphs will no longer be bred or offered on the open market by breeders. Then people will be forced to buy them from the petco's and petsmarts of the world.
