Pigs.

I almost entitled this Porkers but on reconsidering the shot I realised they were much larger than we reared for pork when I was teaching.  They are more the size of baconers.  Breed isn't really a possiblity as they are most likely to be a modern hybrid.  They certainly don't look like any rare breed I have come across.

Clickychick and I went for an afternoon stroll along one of the public rights of way round the village.  As we passed along the road we  could hear them contentedly grunting among themselves.  Turning on to the path we could be seen by them.  For reasons unknown this excited them and they came galloping across.
