If you are driving or walking along next to a field of sheep and see this:
Please if you can stop and turn the poor sheep back on it's legs.
It will be heavily pregnant and got itself into this position by trying to have a scratch, it is known as "cast"
If left it is not uncommon for Crows/Magpies etc to land on them and peck at their stomachs and eyes.
Obviously you'll have to wade through all the dead Badgers and Foxes the Farmer has chucked there but it will be worth it.
