I would add a little chicken broth, kibble by itself is boring. Have her teeth been checked? Any discomfort would make it hard to chew.
She may be going through an adjustment phase.
Some dogs are sad and grieve their former owners, give her time. Also, I hope you aren’t free feeding. Always have fresh water available.
Offer her a meal twice a day at the same times, if she doesn’t eat after 10 minutes pick it up and store in the fridg, offer at the next mealtime.
Dogs thrive on routine, it might take up to a month before she has settled in her new home.
I would consult a vet if she goes 72 hours without eating or drinking water.
