Hi everyone! This is my first post here and I have the age old question of how to keep a goat in a pen. I have about a half acre plus fenced in with horse fencing put up about 8 inches off the ground. Was installed to keep my mare at home before I ended up boarding her again to have an arena to ride in. Now I have two lovely Saanen doelings still on the bottle they are in a pen close to the house for now but they are going to start their escape if I don't get their space ready. Looking for advice on a good charger to run a hot wire along the bottom of the fence and was curious if a top wire would be advised also. I want to be sure to get something with enough bite that coyotes and dogs are not going to be a problem and keep the girls where they are supposed to be. I live in Ohio and am close to Rural king and Tractor supply if either one of those have good choices that would be great. Thanks in advance.
