Ok folks. The verdict is in.
We may be slightly biased, but we did a taste comparison.
We bought a chicken from a local grocery store (one of the nice ones, too) and BBQ'd it alongside our own plump bird (which, by the way, didn't even compare in size. Ours was huge!) and the jury came back. Especially when it came to the breast meat, there was no comparison. Ours won hands down. It was juicer, bigger, had more flavor...you get the drift. Just thinking about it makes me want more. Good thing we know how to make a killer chicken soup with the leftovers!
