It is that time of year.
Yes, I think some of the replies have been a bit harsh so far, though I know they are well meaning.
People sell sheep at market that are due to lamb. CEW has bought nearly forty of them, a couple are having problems, and those are being treated appropriately. There's also no suggestion that they're emaciated or anything, so why the panic measures?
They've been moved now, so surely the best thing would be a several small feeds a day with ewe nuts, maybe supplemented with high energy buckets. That and a quiet life, as MF says.
The point about vaccines is a good one, and whether it's worth it surely depends on how stressed they are at being handled (with most of our soppy sheep, I could just walk up to them and jab them whilst they're chewing the cud - commercial mules, possibly less so!). Apart from that, what am I missing?
