Dogs react differently after switching to raw, some will go through a detox period and that can include signs of allergies. Bear in mind, when you switch to raw from kibble, you're completely changing your dogs diet - you're removing sugar, starch, carbs and others from their diet. It's a big change for the dog.
That's not to say it's not allergies, it could be the chicken, just not enough time has passed to truly know. There are 2 ways to find out - either an allergy test (quick and $$$) or single source protein trial, a protein that your dog hasn't had fed before - and only feed that protein for a month or two. You could also try a vet recommended allergy med for a few days to see if there's any effect.
Maybe give your dog a soothing bath, and follow up with rinse water with coconut oil, see if it makes a difference.
