don't feed her again before you ship her. she's better off being with no food in her while being shipped. also 2 1/2 weeks is nothing. don't have someone else that doesn't know what they are doing feeding a snake that just went thru all that stress being shipped, plus being in a new enclosure. the 2 1/2 weeks that she doesn't eat waiting for you, will give her time to settle into a new place to live. I would tell them to just leave her alone, no handling and this will help getting her back on feed. even if you was flying and being there the next day. the snake still needs time from all the stress and new enclosure. it might take longer than 2 1/2 weeks to get her to eat again. best to setup the tank with proper heat, humidity ect... and make sure there is clean water and leave it alone, no handling.
