Is this true? Need some clarification.

My roomate picked up a corn snake 3 weeks ago at the whiteplains NY show. He didnt ask if it was feeding. 3 weeks go by, and it still hasnt eaten. We tried EVERYTHING! So monday night we force feed it a pinky tail, and it take it down on its own once we helped it get started. Last night we force fed it a rat fuzzy leg, and again, it tok it down fine once we helped it get started. We also noticed last night that the eyes had that hazy blue look to them that indicates a shed. We dont know if it had shed before. Is it true that they dont eat until after their first shed? So far, the animal hasnt regurgitated, and seems ok with eating once we help it get started....Im not quite sure what I am asking, but thats the story. Do you all think everything is OK?
