First of all 8 days, although seems very long to us as humans, is not very long for a snake to not eat. In fact I think I read a recent post here by someone saying he had seen hatchlings go 10 WEEKS before deciding to eat!
Secondly, and I'm purely taking a shot in the dark but I'm thinking this is your first snake and you probably just got it not that long ago. Umm...maybe 8 days ago...lol
The best advice I could offer would be...
Let your new captive settle into it's new home without ANY disruptions. I tend to leave new arrivals completely alone for two weeks! I know this is hard, especially if this is your first and only snake! But this means no handling or feeding! This gives them plenty of time to settle in to their new home and calm down. It also provides time for the new baby to get plenty hungry, even if it was on a vigorous feeding scedule at the breeders! Thus you will have a easier time with your first feeding if your snake is especially hungry!
After the two weeks, offer a small meal. Even if you were told it was eating two pinks, feed it one. If you were told it was feeding fuzzies, offer it a pink, etc. A small first meal is much more easily accepted and digested than a large meal!
And lastly, I find like Flygning said, sometimes hatchlings feed much better in a confined surrounding. Whether it be a small paper bag as mentioned or a new or cleaned deli cup! Another thing to consider is time of day. In the wild corn snakes will normally feed during the evening hours or very early morning hours (sunrise and sunset) I have several snakes in my collection that simply won't feed during daylight hours, but after night falls, they will pound down mice like the best of them!
So there you have a little food for thought, I hope it helps! Part of becoming an expierenced herper is trial and error, finding what works for you and your indivual animals. All snakes are not the same, some will react differently and some will having different feeding responces!
Hang in there and don't get too antsy, I'm sure it will end up just fine for ya!
