Sams Club raw whole chickens are gluten free. (Post below can be found at the gluten free weight watchers blog.)
I double checked the status of the raw whole chickens I buy. When I read the label yesterday it said the ingredients contain "chicken broth". I know a lot of broths have gluten so I shot an e-mail to Pilgrim's pride. Their website did have a listing of items that are gluten free but I did not see whole chickens.
It looks like they are GF (see below).
