Hi Sara,
Raw chicken being a common source of salmonella is not my opinion, it's fact. Dogs are less likely to be affected by it, however, since their digestive systems work differently than ours. It does not mean, however, that it is impossible to make them ill. I'd suggest you ask your vet.
If you do a Web search on chicken and salmonella you should find a lot of articles on the topic, most of them aimed at proper cooking and care when handling raw chicken for people.
I've known people whose dogs have had serious problems with raw bones, so I personally choose not too feed them. Chicken wings included. If I could find large knuckle bones, which can be gnawed but not crunched and swallowed, I would give those to my dogs for "recreation" and teeth cleaning. ( I have small dogs.) None of the butchers near me have them available. So it's my opinion that the risk of feed raw bones, like chicken wings, outweighs the benefits.
By the way - I also give my dogs things like rawhide - which I personally have had to pull out of my dog's mouths in the past to prevent chocking. I stay away from Greenies too - which are not fully digestible, despite the way they are advertised. So I am not anti-raw or anti-bone necessarily.
