I am helping a friend out with her 2 potbelly pigs . She just moved and doesn't have a place for her pigs to have their babies. They have lived only on pasture and when I picked them up on Wednesday I asked what she feeds them and she said grass. They look so skinny to me (except their big pregnant bellies). I can see their hip bones and ribcage. So now they are at my house and I started feeling them mini pig food along with alfalfa. They are due any day and this is my first time with farrowing or keeping potbellies. Any advice would be appreciated. The first pic is Babe and the second one is Willie.
