Yes.
But there shouldnt be any drafts, the bigger the group the better (can cuddle together), plenty of hay for them to snuggle in, also fleece blankies and cuddlecups are good, and could you possibly get a heater into the shed? extension cable?
But anyway, you better wait for the experts to come online, I only kept rabbits outside and that was ages ago, so I am not exactly the outdoors-piggy-expert lol
