I strongly disagree with the advice not to age the venison. I base this on my lifetime consumption of approximately 65 animals, all harvested in southern Ontario. I've tried all scenarios and this included both sexes and variable age (fawns, yearlings, adults). I have a well insulated shop that I can usually manage to keep at near optimum temperatures during most years. This year was great for hanging - managed to keep the carcass at 3 - 10 C air temps for a full 8 days. Even on the day with the 10C air temp, my electric thermometer still showed a carcass meat temp of 6 degrees.
Some years - out of necessity due to warm temps at harvest, and forcasted warm temps in days to come - immediate skinning, approximately 20 hour hang, then butcher. Steaks and roasts are noticeably tough (probably still affected by r. mortis and muscle fibers are still contracted). flavour totally lacking. I wouldn't say bland, rather more like a sharp metallic, "iron blood" taste. Same inferior taste even noted in the grind when used for things like shepherds pie, meatloaf. I'd compare the meat experience to that of commercial pork loin chops - the meat looks great then you cook it and you eat a bland, tough piece of meat with no taste
Fawns - I've had better results for texture (tenderness) on short hangs (1-2 days) when compared to adult deer.
Based on me and my family's and friends opinion - best tasting venison is by far from animals that have been hanging for at least 5 to 7 days. No "blood metallic" taste, definately more tender, esp. roasts and steaks. Very noticeable in cuts from sirloin tip, hind rounds, rolled shoulder and neck roasts. Loin cuts definately more tender.
I do not have a meat locker so I don't have the ability to hang longer . I would if I could ! The best venison I've had was from dry aged carcasses that hung 10-14 days. Problem is finding a butcher that will be willing to have it occupying a spot in their meat locker for that long. For a few years back in the 80s we used to get this done in Lindsay at DeKoker's.

Check this out. Seems like a pretty fair trial.
Re: skinning - I definately skin right away if temps are very warm at harvest or I can see excessive damage from the shot, Otherwise I prefer to leave the skin on until butcher day. It will insulate the meat and keep it cooler on the days when your shop temp goes above the optimum 4-5 degrees for the day. A skinned carcass has no thermal blanket and the meat temp will rise to match the air temp. I also don't like the meat waste and the extra time it takes to trim black rind off all the meat.
