I’ve just started inside lambing ewes were fluke doses with closantol based drench after scanning at new year. Ewes have been inside a month now give or take. Years ago we would lamb bit later well into March and ewes would get a wormer normally zermex drench before turnout with lambs . This time with them not being out much since after scanning should I just turn out ewes with lambs and dose the ewes when lambs get there first dose ?? That’s what I did last year . Also was being told few people give the long lasting zermex jag behind ear at turnout ? Never done that before
