We had minks suddenly appear last winter about this time. "One of them "almost" got into my rooster shed. I normally bait my box traps with marshmallows, but for the mink I used old sandwich meat. It worked very well for me...if this information can help at all.

Thanks for the tip. I tried cat food. and he turned over the trap to get it. Next is a piece of fish anchored inside. However, right now everything is covered with snow and I haven't spotted any tracks in the area so will wait. My coop is secure but I want to remove it before I let young birds out in the spring. There is a big fisher in my woods and I really don't want to lure it closer.
