your a star mate, lad said he would worm them before dropping them of next week, and they were dipped not long ago so I wont need to worry about that till spring? does that sound right? theres 3 small fields to alternate them on so hopefully there should be plenty of grass for a while anyway, but I am gonna get a few bags of sheep nuts just get them coming to the bucket, but read somewhere that they a very sensitive to copper and something else? would there be copper in sheep nuts?
