Have had it thawed and in fridge for 3 days or so, and not noticed any smell.
On the other hand I have often bought chicken wings from well known supermarkets and after 2 days they have had a noticeable whiff! [Noticed in all cases these were ones produced outside the UK, so read your labels].
While dogs are well equipped to handle carrion and going-over meat, I was not pleased to find human quality chicken wings lasting less well than pet food!
