Only just read this but I am pleased things are sounding better already
A few years ago one of my ewes decided to lamb in a ditch and when I found her she was completely paralysed in the back legs. Got her to the shed and it was suggested she was put down. But she looked fine in herself to me, so nursed her for a day or so then got my chiropractor to call out as by then I thought it was a twisted back. We got her to her feet he did the crunchy bit, she bleated then walked out of the shed and started eating.
She reared a cade lamb that year and went on to twin next year with no assistance. Just thought I would mention it.
At the time the chiropractor charged me £30 and the vet wouldn't have been any less and then I would have had to dispose of the carcass.
