The light snowfall in the bottom field has emphasised the paths that the sheep make when moving from place to place. They have definite thoroughfares, and all the animals, not just the sheep, usually adhere to them. Here we see two paths merging into one and heading off towards thee treeline of the bottom field. The paths look whiter than the surrounding green-white of the mildly snowed field. Hoofprints are visible going down the paths. Over at the left of frame halfway down - what's that? Looks like wool to me! It's the boys, all in a cluster, and I think I've been spotted!
