I have some of my ponies on a friends fields. There are a couple of ewes in with them. To be honest, the owner knows nothing about sheep, and if anything happens its me and OH who deal with it, and also sort out worming, shearing and everything else. These ewes are wild, and take some catching. Anyway, a few days ago, my OH noticed one of the ewes looked weak on its back legs, and this happened before with some other sheep in that field, and we lost them. A neighbours tup got in the field during October, so its possible they could be in lamb. Hard to tall, as they are Shropshire sheep and have a big fleece, and getting near them to check for lambs was nigh on impossible.
Found one of the ewes down on the floor yesterday, then she seemed to make a recovery and walked fine with the other ewe. This morning OH found her down again, so has got her and the other sheep in. I am thinking it could be twin lamb disease, or maybe a mineral/vitamin deficiency, but like I say, the sheep seemed to go ok, and then went downhill again. These ewes have been on a big field all winter, and have access to the ponies haylage. Yesterday, I did notice that although one looked very well, and from what I could see big enough to be carrying lambs, the other one, who keeps wobbling over, looked poorer, and its fleece seemed to be duller, and coming out in places.
We did call the vet to one of the others that went like this, and although he treated it, he did not seem clear on what it was.
So any ideas, appreciated.
