I brought 2 piggiess( both girls) ans after 2 months of having them they both had a baby each . when they were giving birth we didnt interfear once apart from a few hourse later wen i cleaned thebed section out ans i held the baby and the mother didnt disown the baby at all. so all i have to say is keep th hutch clean make sure the mom has plenty of hay & fresh food and let her get on with it
hope your baby piggies tun out well x
