As a former deer processor I can tell you that 34 degrees is ideal to hang a deer for an extended ammount of time. That's what we keep our cooler set at. With temps in the 50's hang it in the shade or a garage as suggested, prop open the body cavity and place a bag of ice in it daily.Get that deer processed inside of 3 days or you may regret it.
That's my 2 cents worth...
