Normally at least a week but not more than 2 if I'm selling it on. (My chiller is set to 3 degrees).
There's a rough guide as to maximum based on temperature and time and the number forty - I'll try and explain.......
The theory is that you shouldn't excede 40 frige days at 1 degree, or, a combination of temperature and time not to exceed 40. ie. 20 days at 2 degrees, 10 days at 4 degrees, 8 days at 5 degrees etc......
Obviously wild game handling guidlines require us to store at 7 degrees or below which works out to about 5.7 days at 7 degrees.
This is only a rough guide though and each animal should be treated individually with regard to size, time taken to get to chiller, humidity, contamination, personal taste, etc,,,,,
Hope this helps and makes some sense?
