I put my 2 piggies in together almost four months ago. my abby sow (9months now)and my 2 1/2 year old boar. Neither of them have been bred before and i'm not sure if my sow is pregnant beccause she has always been quite small and although some days she looks a little fatter than other days she doesn't really show any signs of pregnancy. I'll have to seperate them soon anyway before she gets too old but i was wondering if anyone thought trying a younger or proven boar would be advisible. Thanx.
