I have a problem with some curious horses that share a pasture with my chicken coop. They are beautiful animals, however, their curiosity in my coop is bending my hard-wire, creating a potential problem with damaging the run to where pests can get into the coop. They also scratch their bottoms to the corner of the coop and nearly tipped the entire thing over, the movement itself has ruined the hard-wire to the bottom of the run. I have had to replace chicken and hard wire twice since moving in 4 months ago. Any ideas on how to train the horses to either stay away from the coop or perhaps to not be so rough on it? The chickens squack and the horses surprisingly don't get spooked. Any suggestions would be greatly appreciated!
