Ewe losing wool in chunks

Is there any yellowish crusty looking skin/colour where the wool is falling out?

if there is then it may well be scab but you would think they would be itching along with the rest of the flock as if one has it them all have it.

Clik has no effect on scab mite, Invermectin, Dectomax or Cydectin are pretty much useless against scab now so the only real way get rid of it is plunge dipping with diazinon dip.

I heard somewhere that a ewe as you describe has/is recovered from some form of sickness or ailment in the previous couple of months.

Plunge dipping is a great job. A man I know that buys lambs to fatten mixes up his own dip in a concrete trough and dips them in it.

Hard to tell but fluke would be a possibility. What with & when we’re they last dosed for fluke?

well i used to have a ewe here that used tp lose her wool every year so if its not scab would .t be too worried about here as i just used to pull the lose wool off of her to stop here losing wool all over the field

You will have to to the whole lot.

I think the ewe was 'sick' and recovered. Wool loss can be down to a high temperature.

+ 1 on all of that, There's far too much ivermectin used for scab and that's why it's useless for worming now on a lotof farms.

I add aluminium sulphate to the dip as well to heal cuts and help the feet, it would be ideal for Kmacs case where the skin of the sheep is cut, it'd even be a help if you were power washing them.

I usually go double what you would for plunge dipping as it will be not as long as 1 minute submerged as you would in a dipper, dont sue me now if you get parkinsons disease from it, make sure wear good mask, googles and gloves as it will be alot more concentrated.
