Regarding Rhododendron. We had 3 sheep escape thanks to a kind walker and they all ate some thing out of the neighbours plant collection. They were all dribbling from the mouth, stood hunched and making some absolutely horrendous noises when we got home. They were all bloated so we treated them for that as at that point we didn't know they had been out. But they all did something I have never seen a sheep do before and that is vomit, and I mean projectile 10 pints comedy TV style vomit. All anyone I asked could suggest to me was that it would be Rhododendron. One went down that night in the rain and never got up again. One went down the next morning and looked emaciated by the time it eventually got up the after a day and a half and the other one never once went down. She staggered and swayed, looked dead on her feet but never gave in. Both of those have now seemingly recovered 100%. The one that died was the biggest and best ewe we had, a massive thick set Suffolk, and also the greediest so I am guessing she ate the most. The neighbour doesn't think they had any Rhododendron, and there is certainly nothing obvious on investigation, but that is what the dead one had eaten, and not much of it either so it doesn't take much to kill even a big strong ewe. The vomit from one of the living ones had one tiny leaf in it. That is it. Horrible stuff to sheep.
