Just one comment on
timing of tagging - speaking as one who has spent the morning
removing some tags from hoggs ears because the flies had been at them
We are decided to be more diligent about tagging keeping ewe lambs in October - well before the cold weather hits but well after the fly season. And / or to just spray heads with Crovect routinely in fly weather in young sheep recently tagged.
I rarely comment about tags because the whole thing makes me so mad
