Not sure where you live, or even if it a option, but dispatching the fisher might be the easiest method of getting rid of the problem. If you're in a area where it's not safe or legal to shoot it, maybe a licensed nuisance trapper could help out. A hot wire could help, but if there are limbs over the top of the coop and run it be difficult. They are incredible climbers so make sure the top of the run is covered and secure too.
