you would have to cross fence and have a high stocking rate, and rotate pastures to really "keep it down". otherwise the goats will just eat the choice bits and leave some stuff out of control. it depends on what you mean by keep it down too. if there is some brush trying to make its way into your pasture than they might help control that. if you want to keep the grass short its a little harder. if the goats are eating grass you want it tall to lessen intestinal parasite problems. they really don't make great lawn mowers. horses from my experience and I am told sheep do a better job of that. goats are more understory clearers. if you did it right you could make it worth your while though. you can buy wethers pretty cheap, and there are many needing pet homes. I'll sell you my lamancha wether cheap!!! but I'm up in oklahoma, shucks. you could probably get some free, if you really looked around. you just have to be careful that you are not buying health problems. look for local dairys, check out your classfied ads etc.. I would personally stay away from the auctions at least until you get more goat experience. breed wouldn't matter if they are pets, just get whatever strikes your fancy and is available and healthy. good luck! I'm sure someone from your area will probably see this and jump on the chance to sell some of their boys to someone who is not going to put them on the barbi. many people hate to see that fate befall them.
