On a morning walk I came across a lamb with one leg caught under a fence.
The paddock it had been in had plenty of feed.
The grass in the one it had tried to move to was definitely not greener, nor was it more plentiful.
The paddock it had been in was full of other lambs.
The one it had tried to move to had none.
I wondered why a herd animal would leave its mates and lush grass to seek less green and more lonely pastures elsewhere.
Then I saw these two tweets and realised sometimes the question why has no logical answer.
