Thanks, Sally - there is a very robust management programme in place already... It just seems such an unbelievable input in time at the moment, plus it's stressful for the sheep, too; I was hoping that maybe with the vaccine my friend could get away with not doing feet just about every day I go over there... Especially since her husband can't do much (back problems), and my friend works night shifts as well as doing all the hard work on the farm - and she's not getting any younger. either!
Should have thought of Moredun myself - actually have a brochure here beside the bed - thanks for reminding me!
