Hi, all! I'm going to the shelter to get 3 more pigs soon, I already have two sows and I'm getting two more sows and a neutered boar. I was thinking of building a 3x6 C&C cage with a 2x2 loft. (Obviously with a ramp, too.) Is this large enough? I really don't want to do the minimum, I want to spoil my piggies beyond compare!
