Fried food? Bacon grease? No wonder her guts are out of order!
If she were a human, I'd say try grinding a few soy-base bacon-flavored crumbles in Jerry's bean recipe, and see if the familiar flavor will attract her. VERY few. Frontier Herbs sells them without artificial color, and made from organically grown soybeans. Jerry, are these things safe for birds? They certainly can't be worse than bacon grease, can they?
