I am really sorry about your ewe. There were hardly any acorns last year were there.
I'm really glad you've started this thread. All my sheepy friends have been seriously taking the pi** out of me for going to the following lengths:
We electric fenced off under the oak tree line about 4 weeks ago - we have a 500metre stretch with massive oaks to contend with and there are more acorns than I've ever seen in my life and they are still falling! We took two lawn mowers down there yesterday - set them as low as they would go and mowed them up
- it was a bit like hoovering! The grass box filled in seconds. Ended up with shredded acorn and leaf mulch which we tipped over the fence line. Can't hope to get them all though and still have half of the tree line to do. Presumably they get less toxic as they lay there a few weeks - and less appetising? God I hope so - as fencing off the treeline is also fencing off a lot of their natural shelter.
I don't feel quite so stupid now. (Just as stupid as usual)
