I read something recently that disputes that assumption what they said happens is the mink kills one chicken and then tries to drag it out of the coop through the small hole that it entered through, and it can’t get it through,, so then it goes back to look for another chicken to kill and try to drag that one out, which she also can’t get through the little hole and so on and so forth until I guess he’s finally able to get just a head through the little hole. So it’s not really for sport. but they are trying to get food and bring it home to their family maybe?My husband went out and walked the property with the rifle but of course that didn't result in anything. We can't put traps under the coop because a family of groundhogs lives under it and they're harmless. Minks/fishers/etc. are so disgusting, they just killed them all for sport. 2 Crevecoeurs, 2 Favorelles, my second Cayuga. Only took one head.
