I'm new too. I just joined YT on Sunday. (Somewhere in the general discussion is the thread I started "New & in Iowa" - if you want to read about my 2 yorkie babies.)
What a cutie you have!
I wouldn't worry about feeding chicken right now - actually my vet thinks it's best to feed fresh meat, vegetables and such with added supplements. We use Flint River Ranch which my dogs just prefer over anything else and the food is high nutritional product with natural ingredients.
Welcome to YT!!
