Thanks for the feedback everyone.
Well, I revisited the ingredient lists. Apparently, when initially researching these products, I had convinced myself there were no "additives", just organic fruit, nuts and seeds. Wrong. At least for Higgins, the package does say "no artificial flavors or preservatives", but there is a very long list of what I would call "additives and enrichments". These have to affect the flavor. Goldenfeast has a few "fermentation products", but not all the artificial vitamins that Higgins has.
Now that we're down to one conure that doesn't eat fruit, I was really only looking for an economical way to buy safflower seeds as training treats as well as a few nuts he can chew on. I'll look elsewhere.

My bird just likes it straight. He eats what we eat—fruit, nuts, veggies. I have to tell my husband to stop eating the bird’s nuts! The two of them fight over mango. My bird will not eat dried fruit. No way, no how. I store all nuts in the freezer and take out about a week’s worth to leave at room temperature. If he won’t eat a nut, it must be rancid!
