Rex/Lop living situations?

I had 2 rabbits ( a rex and a mini halland lop) and i kept them outside in a hutch. I also built a pen about 10X10 around the hutch and made a ramp going down so they could go outside when ever they wanted. thay loved it. Durring the winter when it got cold i coverd the hutch sides with carpet and filled it with bedding and they stayed warm and comfy all winter long and durring the summer i would freeze big water bottles for them so they could stay cool. My hutch was about Large Hutch (46.5"L x 24"W x 34.5"H) for 2 rabbits so cut that in half for one. and i dont see why they wouldnt get a long with pigs as long as they arnt sick
