Try making a mash by mixing crumbles(or the dust from the bottom of the bag) with some water. Doesn't have to be warm water if it's dust, it dissolved pretty fast. Make it so that it's wet, but not enough that it will slide if you tilt the container. If she won't eat that, add a bit more water to it. Then dip her beak in the water on top. That way, even if she's not eating, she's still getting some nutrition.
