She's a little stressed out right now. Just got moved to a new home, and I assume she's an '03 hatchling, since you are feeding her pinkies. Now that she just ate...Leave her alone for a few days. Don't mess with her at all. You want her to feel very safe so that she keeps her food down.
Yes, she will hide quite a bit, especially right now. Yes, she will almost surely calm down over the next several months. Once she has fed several times and kept all of those meals down, begin gently handling her, making sure that you give her 2-3 days "peace and quiet" after each meal. Some folks say that a day or two is fine, but for a new baby I would give her 3 days, handle her on the 3rd, 4th and/or 5th, and then feed her again.
But let her settle in for a few weeks first. Good luck. You will be amazed how calm she will be for you very soon. Duffy
