Just give the little one time to settle in before you try to feed. Also that shoe box will be great if its a plastic one and not cardboard. You can make a humid hide out of the opaque plastic box by cutting a hole in the side or lid just big enough foor her to get in and keeping damp sphagnum moss or terrarium moxx in it. Its great for when they shed and need the extra humidity. Then if your humidity in the rest of the enclosure isn't great you have a safe guard. Also if the hide is a little big then you can jam wadded up paper towels in it to make it a snug comfy fit for her. I wish you all the luck with your new addition. What did you name her?
