So my corn snake is about a year old, and for the last several months he has been eating three pinkies a week. He's a great eater, never had a problem with him, but feeding three pinkies a week sounds kind of pointless. The problem is, I'm really worried that if I give him something bigger, he won't be able to get it down. His head and neck are very narrow. Is it insane that I'm feeding three pinkies rather than moving up? Do you think he's getting enough nutrition from the pinkies??
