has she shed for you yet? if not you may be surprised when she does that the color is WAY different. The last owners, how much do you know about them? 3 sheds in two years....that’s not right...at all. from the pictures you linked only the second one look like a layer of old skin may still be on (to me anyways). seems like you are really passionate about the health of the animal which is great! Going off your post i'd say she is doing just fine. Hopefully her first shed with you is a good one, if she does have sheds that have not come off having the correct husbandry will resolve that over time. Keep us posted especially the next time she sheds
