You should be ok trying to feed, you just experienced a bad shed. You could set up a humid hide (damp sphagnum moss placed in its hide) and it should take care of itself after a while. I'm pretty sure other keepers will tell you to soak the snake in about a half inch of water for about 45 minutes, then let it run through a towel in your hands. Sort of an assisted shed. And others a damp pillow case, not my favorite idea. Ever try to breath through something damp? So depending on what your comfortable with, there are some suggestions for you. Hope it helps. Next time try the humid hide as soon as you notice your snake going into blue (milky eyes). That should avoid a repeat problem.
