^^^ That. Too many variables to otherwise guess - depends on sanitation during butchering, temps while butchering, what's in your water source, how cold the fridge is, etc... Can't go by the USDA, they say 1-2 days, but that figure doesn't count the time the bird spent in processing, packaging and packing, shipment to warehouse, shipment to store, time "in the back" or allowable time on display before those 1-2 days get added.
On the other hand, we have 1,000s of years of evolution geared, among other things, to selecting for noses that can detect things we shouldn't eat. Your finger is a good judge too - touch it, if it feels slimy, mushy, or otherwise mucous-like.... Not good eats.
