I agree with Nomed about feeding your snake in another container. It just makes life so much easier and less complex for your snakie. You don't want him to think Every time you reach into his viv, you may be dropping food. It could lead to the little guy/gal also biting at you unintentionally. (well.. only with the intention of food that is..)
I had recieved a corn that just Refused to eat for me. For a very very long time. I had been talking with a vet (who has owned corns before, and is considered exotic) and eventually came to force feeding the poor guy for over a year and a half. I tried all sorts of tricks with him. Braining, washing, pinky heads.. everything.
What finally worked with my guy was Fast thawing. Dump the little pinkie into a very hot cup of water. Even if it cooks it a little it sometimes works. Now my guy is quite healthy, never misses a feeding, and is growing like a week.
(just don't intentionally try to cook the meat. Let it sit in there till it's rather warm, and it's still firm. I usually give it about a minute or so depending on the size. For a little pinkie? I figure 30 seconds would be plenty)
Don't be scared if it smells a wee bit funky, er.. well funkier then normal I would guess. *laughs* When they are real hot they smell gross! Then let it cool for a few (don't want to burn your snakes mouth) until you can touch it without feeling it very hot. Then pop it in the small feeding container with your snake and let it explore.
Again, am not an expert but this is what worked for me. It takes a Lot of patience to get a stubborn snake into the habit of eating, but I find once you break him out of it, they become great feeders. Mine never misses a meal now, and all his natural instincts have come out. He bites and strikes and even wraps around the poor thawed mousie
Also listen to a lot of the other posts (listen? heh) on here. Especially in the feeding problem threads. Lots of good information here if you look, and eventually something is bound to work!
Just don't give up
Keep safe
