Like Nic says, You probably have more hogs than you think; quite often they will swap places with another in between clips, just to keep us human servants guessing. I have put a few clips together of their mating behaviour on the doorstep the other night, including an initial brawl between two males. The ‘lady’ in the clip is a youngster from last year and she is a bit of a tease to say the least. She cosies up to the males in the feeding bowl, takes over the food supply and then starts pushing them around, even though they are twice her size! The males usually circle the ladies for quite some time, but this was made a little difficult by the presence of a saucer and a water bowl. He eventually gave up and walked off, only to be followed down the step by the seemingly disinterested female. They could still be heard huffing over two hours later!
