a shame because all the honey comb that was outside was all good healthy brood .they have seem to of left the outside to fend for it’s self
If the bees have gone in then it suggests that the box was empty and there is only one colony.
Your job starts now: take a work tray, knife, empty frames, hive tool, rubber bands or masking tape, water (sticky job), waste bags.
Set up a new floor right next to the current one; use a cut-down pallet for a floor, or something solid; anything is better than the current floor
. Set the floor level.
Move the brood box on to the new floor; leave the roof off.
Dismantle gently the current floor and the white panels with comb attached. Shake the parts abruptly over the brood box and when bee-less, set them aside, away from the hive. More than likely the queen has gone into the box, but look out for her nonetheless.
Remove the rest of the old hive stand and floor and clear well away, so the bees concentrate on the new and not the smell of the old.
Cut the combs and use the rubber band or tape method to fit them like a jigsaw into empty frames. Don't bother to be neat. Slot the frames into the centre of the brood nest. If there is no nectar flow, bees may need syrup feeding to get them to draw and repair comb.
Remove all waste comb and hive bits and bobs from the apiary to avoid attracting robber bees.
Here's one I found this summer: I left the box but took the floor away, waited a week or so for them to move up, then put the box on a board with a small hole and waited another week for them to clear the combs.
