How dry does fur need to be for the tannery

First year trapper, started trapping for nest predator control but ended up developing a new addiction. I have been salting my hides and drying them vs putting them up because I’m just sending them to the tannery. I do want to get set up for stretching and air drying eventually but this is what I came up with for this year. Some of my furs have spots that are dry to the touch but can still bend, they also have not turned white. They don’t have slippage. Do they need to be completely rock hard or is this good enough? They have been up for over a week. I don’t have the greatest temps because I live in south Louisiana but I do have a fan on them with a dehumidifier in the room. Temp is usually about 68.

Even salted skins that have dried rock hard will get floppy in high humidity.
This is because salt is hygroscopic and will draw moisture out of the air.
In either case,the hair wont slip,you can send them to the tanner.
One problem you should be aware of is that if you bend or fold a salted pelt (that has dried hard)_enough to crease it,it can crack and damage the pelt.

Thank you Boco, that’s what I was hoping to hear!
