Hi Tammy, I'm thinking that you want to be able to put it on in the morning and have it done when you get home from work, yes?
I don't have any experience cooking things in a slow cooker cuz mine is sooo old I'm askeered of it! But I hear that crockpot roast chicken is amazing so I wish I could help ya!
I do know that if you defrosted and prepped your wings complete with a dry rub seasoning, then put them in a giant baggy till you get home, you could literally put them on a piece of aluminum foil sprayed with pam or just lightly oiled (which is what I do), on a baking sheet and bake em at 450 for about 30 minutes or until they look brown and crusty on both sides and they'd taste so good you'd want to slap your mama!!! Turn them once when you see them getting browned on the bottom.
To me cooking a wing for 8-10 hours is kinda the equivalent of taking a weed eater to cut down the weeds in a flower pot...
Let us know if you try it and how it turns out!!!!!
