I used liver for bait. I put it on all the dead chicks and put each chick next to a trap. I caught it in a condabear. It was around 11:00 in the morning. It came both nite and day.not always white. My friend who traps purposely asked last time a month ago when I shot the last one if it was brown or white. As they can be either. But yes sounds like you killed a mink. Weasels prefer living food. I can't get a weasel to walk into a baited trap
