I have a weak package hive I installed this April. They superseded from the beginning and have been weak since. They have gone over the last month from 6 deep frames to now 3 deep frames. I don't mind a project and would be willing to try and save them if it is possible. Is it too late in the season to feed pollen patties and sugar water to try and get them to build up? If I bought a new queen this late would she be able to turn the tide on such a small population of bees?
