If the chicken pieces were raw, then it is unlikely that you have much to worry about. Dogs are perfectly adapted for consuming that sort of thing - it is their natural food, after all

And far *easier* for them to digest than things like kibble.
I would be far more worried if she'd eaten cooked chicken pieces, since cooking bones makes them dry and brittle, liable to splinter and cause problems. Or even if it had been the remains of last night's pizza... But raw chicken is unlikely to be problematic, bones and all (many, many dogs are fed this daily, after all).
Even so, since she isn't used to consuming raw food (and presumably may have eaten quite a lot), I would suggest keeping a good eye on her for any signs of tummy upset, and see that she is pooping normally. If there are any troubles of that sort, then a vet visit would be in order. Most likely though, she will digest the raw meat and bones without issue.
