I have 4 whole chickens that are frozen that I plan to cook while camping...and 4 racks of spareribs...How slowly/quickly do whole birds thaw in, say a Coleman Extreme cooler on ice? USDA says 1-2 days in the fridge for fresh poultry, 3-5 days for pork. Any tips on the best way for me to plan this? It's a weeklong trip and I don't care what days I cook... the ribs should be fine. It's the birds I am a little more concerned about. Any advice would be greatly appreciated! Thank you in advance!
