Thank you. If your snake just ate yesterday, do not handle it. If you handle it right after it has eaten then you run the risk of a regurgitation.
Also, I would just feed in the home enclosure. Feeding outside the enclosure only creates more stress for your animal and makes you more likely to receive a bite. It doesn't prevent her from "associating your hand with food". If anything, the association would be stronger if you feed outside the enclosure because you have to physically pick up the snake and move it very close to feeding time and directly after when the snake is still in feeding mode.
