Here in Minnesota we still have snow and are feeding to stimulate
brood rearing.  Are you planning on making any divisions?  If so this is the
hive to do it from.  I personally am more concerned with this type of
situation leading to a brood chamber filled with honey and no room for egg
laying and then the bees swarming.  So I make my divide and relieve the
congestion a bit.  If you are not going to make divides maybe you could give
a few of your other hives some extra frames of brood?
