I was passing a field with sheep but found it unusual to see only the adult ewes out in the field. Under the oak trees were all the spring lambs. It was bitterly cold as you can see from the trees out in the open in the background which were covered with a white frost. It was snowing ever so slightly. Somehow the ewes got the lambs to stay sheltered under these leafless trees and occasionally a mum would come back and feet a young one.
