SL,
Alot of this has to do with size, but if your snake is handling this schedule ok you shouldn't experience any problems. I will say that your snake is going to grow very rapidly. I have some hatchlings I feed one pinky every three days, but two seems a tad much. Alot of this depends on the size of the pinkys also--are we talking day old or week old? Pinkys digest easily, no hair or hardened bones for the snake to digest. Be carefull when the temps drop--with this agressive feeding schedule you may see some regurge.
Good Luck
Matt
