Generally, they won't replace an animal if it laid overnight and was tinted because it wasn't retrieved the day it was killed. The WCO, at least in my state will want to examine the entire animal, carcass and hide before they make a decision that the deer was unfit to eat before it was shot which is the criteria in PA. The OP didn't say where the deer was hit or if it was gut shot. As just stated, I don't know if there was an abdominal wound but I do know that even if it is below freezing, a gut shot animal can turn green in laces over night because of the released bacteria in the abdomen. Just as the hide keeps the cold out, it also keeps body heat in.
