Okay all you people that have goats or sheep or know about weed abatement using these animals: We've got about 1.5 acre plot in our back that we usually have rototilled at the end of the season. I've heard about people renting out goats for mowing down weeds and had a few questions: 1) It costs us about $400 each year to do this. Would rent-a-goat be cheaper? 2) How long does it take a goat to clear 1.5 acres? Would it be safe to assume 2 goats would be half as long? 3) The area is mostly fenced in, but there are some areas I'd need to close up. What kind of fence is required to keep goats secure? 4) Are goats noisy? We've got neighbors on all sides of the yard. 5) Where do I even go to get goats for this purpose. Basically, is there any other info / links people can provide would be excellent.
