had a young roe given to me last week, i hung it in my store outside for 3 days then butchered it. i put every thing in the freezer apart from one haunch which was hung in my spare fridge. how long can i leave it hung in there for as its been in for since late monday night and its starting to turn a dark red in colour. hope this doesnt sound too stupid but its the first time ive had venison outside of a resturant.
