I think i will comment and dispel some myths. firstly when you hand deer it is not blood loss your aiming for and if shot and bled correctly you should have a carcase with very little blood.
You hang in the skin to stop the main mussel surfaces drying to leather like consistency.
animals covered in fat[pigs, sheep, beef etc] do not need the jacket left in place.
Meat is not hung to develop flavour, it is hung to develop tenderness [something more important on bigger or older animals]do an experiment hang two deer of the same type, one 24hrs and butcher the other the correct length of time cook the same piece of meat from both the same way exactly and blind test a few people asking taste and texture and tenderness, the answers will be all taste same, texture same, tenderness longer hung better.
Now if hung correctly the carcase loses a lot of weight by evaporation of fluid/water [reason supermarkets and modern butchers don't like it] partially through enzyme breakdown of muscle.
you cannot give a time for hanging correctly as every carcase is different! my beef was hung from 14 days shortest to 58 days longest to get to the correct stage, age, sex, feed, time of year all have a bearing on how long it takes.
If you cut up a carcase into the main parts you cannot just put it in the fridge and expect it to be hung/mature, it will start rotting fist, go slimy and start growing mold, and regardless of what anyone try's to say, moldy fresh meat is seriously wrong.
if you have no chiller etc , you can still use a fridge by using air dry bags. put a whole leg, shoulder etc into bag and vacuum on machine and seal. put it in the fridge with nothing touching it and turn daily until it done. hope that helps.
