Hehehe Laura
I've got Kunes too - could always work something out
They're really hardy - and as long as they've got company to cuddle up to and a dry, deep straw bed they'll be fine (although, if you're looking for young stock at this time of year you might find they'll vanish under a foot of snow, so unless you've a stable or somewhere inside you could keep them over the worst of the weather you would probably be best either waiting til next spring or buying adults (though that does away with the cute factor of the weaners
)
Mine are out all year, with wee shots in the shed for everybody (except the boar, who refuses to come in !) it was minus 20 winter just past and he was fine - his arc was warmer than our living room
