When I winterize my coops, it is always temporary and will not usually hang for more than a week or two. I have many times stapled roll plastic on the outside and it worked fine for what I needed. Here, Zip ties are fast, cheap, and can be taken down and then redone in two weeks if needed with no damage to the coop.
Maybe you could catch a mouse in a trap and quickly rub it on a papertowel and drop that papertowel or some mouse poop into the PVC pipe that CC was talking about. That way, you catch the mink without killing it and don't have to buy/kill the mouses. I would even try dropping in a dead mouse but the smell of a long dead mouse might not attract the critter. Then you could relocate it a long way from anyone else's chickens, or give it to someone who would dispose of it.
Oh yeah if I can trap it I will relocate it very far from any thing.....
I'm having a hard time figuring out what I can do here.... I can legally kill it it seems but it looks like I can't trap it legally.... Oh well no one will tell on me right?

Any way I appreciate all the ideas.
I wonder if the sent of the ferret would cause it to relocate or just make it feel more at home...
Regardless I will ( or the pets will ) take care of it shortly. I refuse to lose any more birds this year.
