i do muntjac for 5 days
roe for 7-14 days
fallow for 10-14 days
depending on size/age of animal
kept at 6c in the fur , i sometimes use a 50/50% vinegar /water mix to wipe the inside of the carcass out if hanging for a longer time to prevent any mould growth
on the inside of the carcuss [note when i do this the fresh /clean cloth i will use is only damp NOT wet i dont want to promote a bacterial bloom ]
ive been doing this for many years ,i must add this is for my own consumption and only my opinion
hope this helps
