You'll be fine eating those. Birds kept cold are good to go for quite a while. Just two nights ago I returned home very late with three roosters and a sharpie. Golfers elbow was seriously acting up in right arm so I took care of the dogs, downed some ibuprofen, threw the birds in a cooler outside and left them till morning (I knew temp would drop below freezing during the night). Geese are different. I might leave them overnight on the garage floor if the temp dropped well below freezing. They are too big with too much insulation so have to be careful. Uplands will cool down very quickly if weather cooperates. If hot out, better gut them quickly.
