Just saw the pic, and yeah, quickwood or epoxy putty will work well. I just did it last spring to one of mine.
Epoxy putty is very sticky, and once it attaches it's there for a while, so just make sure that it sticks to the box, and not the bottom board. Sprinkle some flour on the bottom board to make sure that it doesn't stick to it if you have to.
I couldn't quite tell, but it looked like your hive was sitting on the ground. If so, get it up off the ground with some cinder blocks and/or some pressure treated wood. If you let it sit on the ground the wood will rot fast.
