Hello all,
This is my first time posting here, I usually just lurk and learn, and honestly this question was the only reason I made my account as I haven’t seen it specifically asked or answered anywhere. Apologies if it was and I just missed it.
So my question is as stated in the title: how long does it last? I’m mainly curious about coyotes and beavers. If I ever manage to catch any, get them skinned, fleshed, stretched and dried, how long would I be able to hold on to them before either selling them or getting them tanned? I see a lot where guys will have the flattened dried furs stacked up like cordwood in their fur sheds, but how long could they stay stacked like that?
For context, I live and (attempt to) trap in western North Dakota, so temps are currently anywhere from cold to downright ridiculous. Is temperature as much of a concern once they are fleshed and dried?
Any tips, tricks, or info is much appreciated!

Once stretched dried and scraped clean pelts will keep in a freezer for several years.
If not in a freezer,they will deteriorate over the summer from grease burn and bug damage.
Even in winter if not in a freezer they are prone to damage from vermin.
