I know everyone on here seems to prefer pigs indoors but there is no way I can keep mine indoors. They are in a pretty big hutch with two floors, then there's the bunny who lives in another hutch . . . . plus when they were babies and I did keep them in for a few weeks, it drove me potty with hay and stuff everywhere, getting on the kids feet and transferring all round the house. Now don't g et me wrong, no-one loves their piggies more than I do but I've had to face it . . . they're outdoor pigs. This is the first winter for four of them but Molly has seen two winters outside and she is in excellent health. . .
My hutch has an upstairs floor which I think is warmer, so they may all sleep up there, I know only two do atm, this also has newspaper, straw (tons of it, like downstairs lol) and they each have little individual places where they sleep ie, little huts & tubes that they sleep in. I'm thinking of getting them a little fleecy bed each. (Minty our bunny has a fleece blanket and he snuggles in it and cleverly wees just in one corner away from it . . . I hope the guineas can be as clever!)
