I found out from the herders how they keep count of the herd. They only need to count the black sheep. If any are missing then they know they need to go back and look for them. About 100 got into our place and of course were ripping out every plant by the roots. There was no black sheep with them, I decided to go find the herders to get their sheep. I tried to get them out...what a joke! Sheep are not the brightest critters in the world.
