Curious as to your thoughts on this one. I have three opinions:
Cocoroco - Overrated. Too salty IMO.
Russo's - I liked this chicken when it was 4.99/bird, but the skin tends to be flabby and not rendered long enough to thin/crisp it.
Uncle Moe's - Maybe I'm nuts, but this is my favorite. The skin is rendered thin and nicely seasoned, and the breasts are not dried out. Nice and flavorful.
I try not to bother with the supermarket Rot chickens, but I've had C-Town and Pathmark chickens in the past, and both were underwhelming as you can imagine.
