She may have parasites, so you'll need to get a sample in to the vet but wait a couple of weeks to see if the stink continues. She's going through relocation stress, which is real to beardies, just getting used to a new place. It can take a week or even two before they feel at home again, and during that time she might not eat a lot, but that will improve with time. If her poops are still stinky after 2 week, then it's time to take a sample to a vet to get it checked for parasites, which don't go away, they have to be medicated. Once they're gone, she'll feel a lot better. Meanwhile, you should get some Acidophiluz, it's a probiotic for dragons, that helps put good flora back in their gut and helps with digestion. Also make sure she gets a daily back, so she stayed well
hydrated. That's important. What type of
UVB light are you using? Reptisun 10.0? That would be the best tube, that's also very important. We'll have to go over your setup at some point, make sure it's good for her. It's always exciting to get a new beardie!
