Grey acting drunk after eating dusted crickets?

[UncleChester]

I don't know about the acting drunk bit, but the half open eyes sometimes happens after eating. All eyelids close on attack and the clear one doesn't always open fully right away.

This morning when I checked on her she was sitting there opening and closing her mouth and had goo on either side of her mouth mixed with the dirt from her substrate and she was still acting off.

This sounds like normal shedding behavior. The 'goo' is her skin that she's shedding, it bunches up on the side of her mouth as she's eating it (frogs like to recycle). The substrate mixed in was already on her skin and goes along for the ride. The opening and closing of the mouth is sucking the skin in. She may have also puffed up like a balloon and squirmed from side to side to loosen the skin and ease the process along.

Hope all is well and if you powder was contaminated that they can figure out with what and how it happened.

What did I just read...

Like Brian explained, the mouth-opening and the goo sounds like perfectly normal shedding behavior, so no worries there.
I would not stop dusting, since the powders contain much of the goodness the frogs need. If you really want to, exchange that specific batch of powder (which it sounds like you already did).
