Maybe the sheep are the ones that see contrails and think they are being sprayed. Contrails have been around since WW2. If the contrails have become chemtrails, what happened to the contrails? Where are the vast fleets of spraying aircraft?
There’s a Chuck Yeager video on YouTube where he mentions flying into Germany in his P-51.
He saw a big cloud bank up ahead and suddenly realized that the cloud was an enormous condensation trail from hundreds of German fighter planes headed his way.
WWII skies absolutely filled with contrails are easy to find.
