I agree Doug. Wild creatures should be free to live as they wish.
We live in a village among a chain of streams, small lakes, ponds, a large watermill and the river Wensum. The number of wild water birds is amazing.
When I sit on my garden bench in front of the house, flocks of swans, necks outstretched, pass overhead, not to mention geese, all kinds of ducks etc. They call and squawk as they fly, and it always brings tears to my eyes. Then there are crows, magpies, jackdaws, swifts and house martins, all making a lovely din (and depositing their gifts all down our window panes, but we have an excellent window cleaner called Andy)
I should have written 'she' for the pig - it was a fat old sow!
