I have tons of tree splings and brush to clear and chopping it down 2x a summer is exhausting. I have brush/woods surrounds my 1 acher yard. I dont know a whole lot about goats other than there are a lot in my area. how often do you milk a goat is it the same as a cow? are they as regimented about milking times as cows? I grew up on a dairy farm so no stranger to milking. just no experiance with goats.
Here is a link to a BYC sister site, back yard herds, with a whole section about goats: http://www.backyardherds.com/forum/
Are you wanting to breed and milk them? Or just have them around as brush clearer's? If you want to milk them then yes, they need to be milked on a regular schedule. And you'll definitly want more then one, they are very much herd animals and a far happier in a group then kept alone. You'll need very secure fencing to keep them in and keep dogs and coyotes out. I use welded horse fence with a hot wire on top, one inside the fence about a foot off the ground to keep the goats off the fence and another strand of hot wire outside the fence near the ground to discourage dogs etc. They'll need a barn or shed to get out of the weather. They will also need their hooves trimmed occasionally and to be dewormed on a regular basis. Goats would do a very good job at your intended purpose. They are not good lawn mowers but are great at clearing brush, shrubs, trimming low hanging branches etc.
Brush clearers won't make good tasting milk. Certain plants will produce an off-taste that is quite revolting. If you want goats to clear brush don't get dairy goats, if you want milk then don't let them eat brush!
