I bought 2 whole chickens last Monday. I've kept them refrigerated the whole time and the expiration date says "use before 8/30." However, the package also says, "use within 48 hours of purchase." Ooops. Would you still use them? I'd really like to do a roast in the oven. It will take 90 minutes to cook (I"m getting a very late start. May have to eat the roast tomorrow and have leftover turkey burgers today. )
