Hi Doing a bit of maintenance on ewes yesterday, GFDs, and noticed some scaby patches on heads of two of them, fleece matted, with small bits in, looks like fly eggs but no sign of maggots surley to early for flys. Skin isnt broken but looks sore in small area. Anyway clipped fleece back and applied blue spray. Not the best looking GFDs now! Anyone any ideas before I ring the vet? Ron.
