I don't believe it is diet: she was messy when she was in on pellets and haylage and still is on my unimproved but clovery upland fields.
She seems fit and well - no sign of discomfort or loss of condition. No odd behaviour.
I wouldn't say she was scouring as such: she produces very sloppy doings which she seems to manage to get all over her back end somehow, but it isn't liquid, yellow or smelly. Just...cow-like...
Definitely cull, you don't want to breed from that.
Having said which, I had a last minute change of heart and kept Harry Potter because her fleece was so interesting. She's still a mucky one, but so far
her lambs don't seem to be following her in that. They're both ewe lambs, so I'll be making sure I know which ones they are and monitoring them closely up until keeper selection time
. I still have mixed feelings about HP though... she's done a great job, has a fabulously sproingy fleece, but she is, always, mucky at the back.
