We saw several cases of flystrike around the shoulders and over the brisket when the sheep were wet through after a very wet WInter a few years ago and decided they had fleece rot which had attracted the flies. It was too early for them to have been shorn. We now Clik three weeks after shearing - along the back, across the shoulders and the top of the tail. This year I'm going to crutch the whole flock before tupping. Our Badger Face get freaked out by flies and sulk in the shade or a field shelter on humid days. The Southdowns seem blissfully oblivious.
