Sadly, I had to put her down yesterday evening - she had made progress slowly and the vet last week said to get her outside for a bit of grass - so took her out a couple of days alone which she hated, then decided to put the yearlings with her, but keep a close eye in case they bashed her. All OK for an hour, took my eyes off them for under 5 mins while i went to open the barn gate - and they knocked her down.
She didn't recover, I think she just realised she couldn't do it and gave up - I definitely got the message from her on Saturday and decided not to force her to drink or eat - and yesterday it was so cold, I called the vet out. In retrospect, she would have had to recover to plus 100% as she had gone blind in one eye and would have had to defend herself on that side.
I have learnt a lot about the disease and will never ever ever ever feed haylage again. Lesson learnt. I know lots of goat and sheep keepers do feed haylage, but as I can make good hay - I'm sticking with that!
Good news: we have 20 happy healthy kids bouncing around the barn!
