I've had a lot of female mink eaten by other mink, mostly during the rut. I just leave um in the trap and set another..

Duck and goose scraps work well in late fall for mink bait.
Grouse scraps work ok before the hard freeze.

I could probably come up with a Dodo bird around here before a grouse. Havent seen one in 20 years and I spend a good amount of time in the woods during the fall.

polluted with grouse here,you can kill them with a stick.

I think you could probably catch mink using pork chops for bait, but fish and rat carcass’s are cheaper and easier to come by.
