I really wouldn’t suggest offering two feeders at her size, hognoses aren’t really meant to eat rodents (in the wild they primarily eat amphibians) and you can grow them too quickly and cause health issues down the line. Snakes will continue to eat even if they’ve already been fed, a feeding response doesn’t necessarily correlate to the actual need for food.
What you can try is mixing up what food items you offer to give a better variety and more enrichment. You can take a look at this post for great suggestions of alternative food items and how to prepare them:
I’ll also ask @ballornothing if he may have some suggestions for you?
