So, they WILL compost? Some friends speculated that they are too hard or that this was going to take decades before we saw any benefit.
(They only come salted, in these serving bags. The individual packages, 99 cents apiece, are just smaller portions... and designed for lunch packs, etc... also salted, though I have seen other brands that are plain.)

UPDATE: We eventually collected an entire individual sized bag of uncracked nuts still in the shell, and took them back to the store. The manager took one look at them and invited us to go select another bag off the shelf. We're very pleased, he's pleased, and no one is the wiser.

Woo hoo, score!

Last year I bought some packages (when on sale) of a brand called - Everybody's Nuts!
http://www.everybodysnuts.com/
They are very good quality and also come with a guarantee that there will be no nuts that aren't open. They will give you a coupon for a free package if you find a closed nut.
The brand is fairly expensive.

After I found out my feathered companions really liked them. (I give them the unsalted kind only.) I later resorted to buying Trader Joe's unsalted brand. I just went there again to buy my first one pound bag in a long time. My new Grey (found outside in Seattle last summer) has shown no interest in them but the other guys were really pleased to see they were back on the treat menu.

Everybody's Nuts are pretty cheap at Costco.

Good to know. Do they have a wide range of the flavors?
I have taken to buying all nuts unsalted so everyone here can eat them (humans and avians) and they were usually the harder ones to find when a store was stocking multiple flavors.
