Yeah, my fence is "starting" to look like that.
Mine are just lambs right now.
I wish I had trees in their current pasture.
I'm planning on planting a couple fast-growing trees but they will be protected with a wire cage for years till they're strong enough to withstand sheep.
I'm mainly planting them for shade since we have one near our house and LOVE it.
Those scratching gizmos that are on sale are awesome but I don't have the extra cash to fork out (they're kinda expensive).
I'm thinking about bolting a push broom (bottom) to a fence post and hope that the dogs don't chew it up before the sheep can use it.
I came across this on craigslist recently.. Made me think of using the head off a wide broom and somehow attaching it to a t-post for my goats. I dont have sheep though so I dont know how hard it would be to clean. http://redding.craigslist.org/grd/3096473262.html
