i didn't notice anyone touching on the subject of leaving the hide on while it was hanging. last year i hung mine for 2 days with the hide in a barn. (it was plenty cold)
anyway a friend of mine had me help him with 3 does he had shot this season.they hung for 4-5 days without the hide. when we pulled them out to begin butcherering i noticed a thin layer of crunchy tough membrane? we spent a whole lot of time filleting that stuff off. for me i believe i will always leave the hide on.
