How long can a raw deer hide ( not salted, with some meat on it) can last at 0-2 degres Celsius so it is still good to tan?? I`m mostly a bird taxidermist and would like to put my hands on some deers.. That butcher has some hides to give me but they have been a couple of days on the deer and after skinning, he just toss them in a corner of his fridge for another couple of days.. Will they still be good for tanning ???? Thanks!!!!
