Shepherds Pie (using leftover roast chicken)

I love roasting whole chickens. I'll roast two chickens at a time, make a gravy with the giblets, save the bones to make chicken stock, and use the leftovers from the second chicken for easy meals for the rest of the week. This weekend I added a new dish, Shepherd's Pie, to the rotation for using up the leftovers. I adapted a couple of different shepherd's pie recipes I've been seeing online for a while now. It's so tasty and pretty easy to make.
