If the fuzzie was dying, was it sick? DO NOT feed it to your snake if it was sick and dying.
You should wait a week or so before handling or feeding your new snake, let him get used to his surroundings.
Stick with F/T, follow Nanci's advice, I have never had a yearling not eat after a few tries. Is he blue? Give him another week without trying and let him get good and hungry. Corns can go a long time without food, so just make sure you have clean water. After the week, put the fuzzy on a plastic lid, cut a few slices along its back or head and cover the tank (I am an "in the viv" feeder) and see what happens. If he hasn't eaten by then, leave him alone with it for the night, see if it is gone in the morning.
Also, what is your thermostat temp set to, and does the thermometer agree with the thermostat?
Is he blue?
I know, lots of questions, but if you answer them they will give us a better idea of what to suggest to you.
