Me,not the sheep!!! Ok so, about to get a ewe and her twins (m&f) in the next day or two,just waiting on them having their 2nd BT jab. I have a field shelter,fresh water, straw and an acre of grass with some shade from numerous trees. Vet sorted,fencing all checked........ what am I missing??? Salt/Mineral lick? The neighbour doesn't use one,but then again,this is France! Help please! ...... Ree
