hello, I’ve got my first piggies after wanting them for years so I want to do everything right. They are only babies at the moment so my plan is one the weather is warmer to put them outside and they can have their hutch out onto the grass but for now they are inside . They have a cage and an indoor run which is larger. I put them in the run during the day with hiding places , food etc and then the cage at night . Although the run is bigger they just hide when they go in there. Is this because it’s a new place for them and they will eventually come out or does this mean they are happier in the cage?
