in the house my girls have a home made barrier which works great and they are quite happy in their space....except for tufty who jumps over but always comes back ;D as if to keep an eye on things.
my boys are a different matter, they come out in pairs but there is no way they would be fenced in. the boys are so different to the girls, they are nosey and seem to love the adventure, the boys are a great laugh, most come back in easy apart from buddy who will only come in when he's had enough :-\ he is a nasty biter and yet a lovely pig if that makes sense. so you don't tend to put your hand out towards him ;D
i have to sit on the floor and tap my lap and he will jump up and run up the front of me to my chest and then gives me a lick and a squeake and then you can give him a big cuddle :smitten:
