I have a normal corn that I have had for a few months now, he/she is 25g now and I have been feeding one pinky mouse, I just checked the munson chart and he/she is overdue to start two pinky mice, how do I feed two pinky mice? Right now it prefers the food left in the enclosure, do I jsut leave two thawed pinkies in there isntead of just the one pinky?
