I have some chicken wings in the freezer in a freezer bag. They have a lot of ice and frost on them. Would they be still good to use?

Ice on frozen food just means that they weren't wrapped correctly or they were very wet when frozen. Wings have added water so they often get icy when frozen. It does not mean that they are necessarily burned or bad.

Thank you all so much! I really appreciate the suggestions!

It would depend on how long they've been in there and if they're freezer burned.

I'd thaw them under cool running water in a bowl..until thawed. Give them a sniff test and inspect for any dried spots (Freezer Burn--white spots). Then a few more rinses of cold water and a couple hours soak in water with a couple table spoons of kosher salt.
Then rinse and use.

Stock is a good reply - assuming they are uncooked. You can roast them on a sheet pan then make stock to get a richer flavor and color.

Personally I would use them to make stock
