It costs as much to feed a normal as it does a quadruple morph. I have limited space for snakes and rats, so my collection is forced to stay small so little choice but to phase out my normals.

I can see the rationale for keeping normals if you have the space. You buy a $20,000 male of a new dom/co-dom morph...you want to be able to put him to as many females as possible to try and recoup your funds ASAP (before the annual co-dom/dom price drop kills you). 8 big female normals could get you 25+ morph babies to sell. Even with a price drop to $2000 ea you make your money back and then some.
