Chinchilla won’t eat oxbow pellets?

Hey so my chinchilla Minchi is usually a great eater and LOVES pellets. She used to eat them like I never fed her before when I’d fill her bowl back up. She’s been on oxbow pellets her whole life (not the garden select) and lately I’ve noticed that 1. She spends a ton of time at the pellet bowl eating slowly and 2. She’s leaving a bunch of half eaten pellets in the bowl (more than the norm for her, and no it’s not crumbled just in half). She gets very excited for the oxbow digestive treats...
