Jim asked about over-wintering a weak hive above a double screened strong
hive.
This probably will not work as the weak hive will not have enough stores.
Better to put the hive directly on top of the strong hive, with no barrier.
Then they will gradually combine during the winter, and you may even end up
with a 2-queen hive in the spring that you can split!
Good luck,
Lloyd
