The fence was ready - coincidentally, just in time for our cows! So, for convenience, we put them in the new barn and the new pasture - which is separated by the sheep lot with just a temporary fence.
And oh yes, here it is.. the reason the sheep will stay on the pasture that they are on for a while longer... burrs!
(fortunately, the burrs come off the cows rather easily - much nicer than they could come out of wool!)
So the cows can keep the new barn and the burrs (for now) the sheep will be just fine on this side of the fence. However, looks like a big spring project is waiting! (fyi - I hear that a vinegar and salt water solution works wonders on killing burrs and weeds!)
