Very humid here on Friday, although not particularly hot. Lambs with sound feet and clean back ends. Four weeks still to go on Clik. Noticed a couple of lambs with damp looking patches on their backs. Kept an eye on them for a few minutes and, yup, greenbottles landing on them. Got them in the shed, slipped away all the wool from a wide strip around the damp patch, then poured on a mix of 100ml Jeyes Fluid, 100ml Dettol in a litre of water. A couple of dozen older maggots and then 49 gazillion tiny ones wriggled out, probably only a day old. Gave lambs antibiotic and painkiller. Now in shed cudding. You have been warned!
