Do sheep need shade? Are lambs more or less affected by the heat and sun than adult ewes. I have shade in all my pastures on 35 acres but now I can pasture a another piece of land and the shade is not so easily accessed. The plan was to pasture the lambs on this new piece and use 4 rolls of the electric netting to make a moveable corral to rotate throughout this field. The problem is there would not be shade. Is that a problem? I am in Northcentral Wisconsin.
