Hi really sorry to hear about your loss. as i posted on the poo picking thread. we used to poo pick every day with a worm count twice a year and 1 worming dun a year about october. if the test came back with a worm count we would worm. we did really well this year all the horses came back with a zero worm count. it cost £10 per horse for a worm count here. cheaper than a wormer. just more hard work
