little late here, but Ive left venison quarters on ice for 3-4 days no problem, before I bought my "game fridge"(yard sale fridge for $75 in the carport).
You gotta do what you gotta do. Especially when you have 70-80F days.
I also let the plug out, so it could drain.

My dog and yard cats love cleaned-out raw leg bones. The cats especially
turn into "little lions".
