SpokaneDude, A #1 skin should have a feather range down to size 20. There should be a number of 16 and 18 – quite a few more than the 20's which always seem scarce to me.
It should arrive clean and the skin shouldn't be so dry it cracks when you bend it. The size of the birds should be good and the bird fully developed.
Color contrast for the light and dark barring on the feathers should be distinct. And finally, there should be fair amount of the mottled brown barred feather on the shoulder of the wing and lower back.
If you aren't satisfied with the skin I'd quickly call or email to start the return process. Don't delay.
Oh, one other thing to remember is that we have grown used to farm and pen raised bird skins. Most partridge skins are bagged during hunting season. You have to really search for a truly "pretty and fluffy" partridge skin.
