Goat’s are great to have around to clear areas that you don’t want to mow or spray. There are electric fence options that you can use to move around to different areas. Premier One has several options. Beware that you need to use a good electric fencer. Goats are notorious for figuring out that the shock is worse than the bite and they will shove other young goats into the fence. They then get tangled up in the fence with disastrous results.
Checking the fence daily and moving around helps keep the goats safe, happy, and your weeds at bay. Always remember goats are herd animals and they need other goats to be happy.
