I assembled a new hive body that is not at all square. It is all glued and I used screws to put it together as they did not sen the correct nails. The first three I assembled came out perfect so I did not fuss over this one. I am hoping they send a replacement, but in the future I will check the corners better. Is there any remedy as you assemble and find the box is not square. Could I have used wood putty or glue mixed with shavings to fill the gaps, or did I mess up?
