Sheep cluster together under the shade of a lone tree on a bright day, trying to regulate their body temperature, and avoid heat stress, as wool affects their comfort. Susan Schoenian, University of Maryland Extension Sheep and Goat Specialist says, “Wool protects sheep from extreme heat as well as extreme cold. A thick fleece is mostly immune to temperature changes due to its insulating properties. According to research, sheep with a one-inch fleece are more comfortable than sheep with less wool, as wool fibers dissipate heat more rapidly.” (https://duraferm.com/2020/08/keeping-the-flock-healthy-through-summers-heat/)
