I wouldn't feed both. I switched my entire yard over to raw some time ago, and I only have dogfood here for the spare dog that comes for breeding that eats dogfood AND for the times I'm gone and the wife has to feed. The only grain my dogs get is some rice, and it's less than 1 cup a day. Some days there is no grain involved.

So no, I don't think chicken along with kibble makes a well balanced meal. Feeding raw is like feeding yourself. It's about balance over time not a balance everyday.
