I have just wormed my ewes after lambing and am now thinking about the next tasks. I am thinking about putting Clic on the ewes as I had a bad case of fly strike last year despite hoping that they wouldn't be too badly affected. My question is, when do I put Clic on my Wiltshire Horns who seem to have started shedding their fleeces? I am presuming that I will need to treat twice this season because of the fact that it only gives 4 months protection but am worried that it won't be effective if they shed after application. Any thoughts?
