So I want to start a more vigorous rotational grazing schedule in the spring. What I currently have are three pastures, all bounded with electric fence. Does anybody know how long a pasture has to be off to effect parasite loads? The other issue is shelter. Me and DH have been cracking wise about building a mobile goat hut (I could train wethers to pull it! it would be a GOAT POWERED goat hut!) but I'm not sure if that's actually feasible. Anybody have a suggestion? Because if it were mobile, we wouldn't have to build as many huts, and could use mobile fencing to divide more finely. How do you guys do it?
