She won't stop dumping her food bowl .... So my Flower has this awful habit of dumping out ALL the food in her bowl.  I got a food bin that attaches to the side of the cage so she can't tip the bowl over, and instead, she digs in the bin and scoops all the food out.  Her cage-mate, Kyle, doesn't do this, and in fact ends up sometimes needing to be fed separately because she dumps all the food.  It's most frustrating because it's a waste of food and it's not cheap!  Any suggestions for what to do about it, or maybe even why she is doing it?  Could this be her protesting the food?  Thanks!
