I'm not sure (from reading lots of advice on here) whether the area we'd be keep them (or what I imagined) would be suitable 
I have a large garden and patio area. Imagined that they could live in a big outdoor cage in the Summer and then (this is where it gets tricky) during the winter I would have to bring them indoors (don't have a garage and no room in shed) but the only room I could imagine we'd be able to home them would be the kitchen and from what I've read on here, this wouldn't be ideal.
The only thing I can imagine I could do is if I'm cooking I could put them in the living room. Kitchen doesn't get that warm unless the cooker is on, no direct sun during the day. Would this be a possibility?
Would appreciate any advice.
