Be very careful with adding different things to her food. You can see she's already started picking out the good stuff. You can actually create a picky eater by changing things up to much. A healthy dog will not starve themselves, they will eat when they need to. She's really new and unsettled right now. Routine is your best buddy right now. Once she figures out the mealtime routine she'll eat better. Right now just put her food down for 15 minutes. If she doesn't eat it all, pick it up and put it in the fridge and put it back down at dinner. Doing this for a few days teaches her she has to eat when it's offered or she will be hungry.
I've had 16 hounds and used this technique with each one and never had issues with any of them unless they were sick. If you have a sick dog, then you feed them what you can get them to eat until they are well again.
