Its unusual for the Queen to leave the nest, i wonder if the nest is not damp enough for them?
Its tempting to disturb the nest if you dont see activity, i know, but you must resist the urge, a young colony will not be very active at all for the first 6-12 months, they dont need much food until the 2nd generation of workers arrives
patience is the key
I expect your colony will be ok, just give them time to recover after the huge giant evil human came and ripped their nest to pieces lol
checkout my caresheet in the begginers section, you might find it useful and should answer ur questions

hope they wouldnt have hibernated if they where inside, they need temps between 1-10C, 7-8C is best
