Answer
Ashley, I'm guessing you have what the industry calls a "jungle corn."  A hybrid between a corn and a CA king.  I would say you should feed your snake once per week minimum until he is an adult.  Also, you should feed him something at LEAST as big around as he is at his biggest point.  Do not worry about how big his neck is, look at his widest point and judge from there.  If he throws up or has runny watery poop, you should take him to the vet.  That's all the info I can give you based on what you gave me.  Hope this helps, BPC
