How are you thawing the mice? I have never had any issues feeding f/t. I am currently making a tutorial video for the forum, but I'm having some editing issues.

You want the mice to smell like mice. Don't thaw them out in water. I just set them out for 45 min to an hour. I like to use a heat lamp to heat them up after they have thawed. I have had incredible success with this method of thawing.

When are you trying to feed? Always try to get new snakes to eat at night in a darker room to increase their comfort too. If you place the snake and hide in a tub next to the thawed mice for a little while. After awhile she should become curious for the source of the rodent smell. I would offer then when her head is poking out from the hide.
