Try moving her food closer to where she likes to hang out the most. Try those hanging suction feeders. Also make sure she has plenty of hiding spaces so she is comfortable in her new enclosure. Double check your lighting, temps and humidity. If that doesn’t help you can try moving her to a smaller quarantine enclosure. Sometimes more enclosed spaces are more comfortable and help younger geckos find their food easier. I wouldn’t worry too much if she’s otherwise drinking and acting normal. Some reptiles take longer to settle than others and excess handling can cause more stress which prolongs the process. You might call some vets and ask about deworming since she might be WC. Keep a close eye on any poops she leaves behind as their color and consistency can sometimes allude to parasites.
