I have my pasture rented to my Amish neighbor so he can winter graze his cattle. Yesterday morning one of the cows unexpectedly calved in about 4 inches of snow. He came and checked her out last night and said things looked good. About noon today, I was in the pasture and did not see the calf anywhere. I searched for it and found it in the wood line near the creek a good ways aways from the other cattle. I led the cows to where the calf was. After a few minutes, the mother moved over to the calf and the calf began to nurse. I then left. This evening, I looked out and did not see the calf again. I searched for it. I found it laying underneath a tree by itself. Is this normal behavior or at some point should I intervene?
