We are feeding our neighbor's sheep and llamas while he is going through a rough family time. We actually only feed ever other day. We went today and found a sheep (ewe) dead in the one field. We called him on the cell phone and told him about this and he said he knew the sheep was in trouble and that he dewormed it yesterday. But he left it in the same field it has always been in. My thought was when we have a sick animal we always seperate it to our "infirmary" area inside and nurse it and watch it very carefully. What do ya'll do in that case?
