Hi Juliettex
Don’t worry – that sounds quite normal. It was likely a male and female and the female would have been huffing. The male normally circles the female as she turns round whilst huffing away, but sometimes during that she reverses and sometimes he loses interest and disappears, so she may be appearing to go backwards more than usual – if he has gone, she has no need to continue turning round.
It sometimes looks as if it is some sort of endurance test for the males and either male or female may get fed up in the middle of the circling and wander off! It’s amazing they ever manage to produce any hoglets at all with all the (sometimes fruitless) circling!
