I'm a new Ohio beekeeper as of last spring. I have 3 hives, Italian pkgs from York. 2 deeps on each. This is my first winter and I made a beginner mistake. Entrance reducers on all 3 but noticed wasps coming and going from one hive regularly in Oct. Hive was horribly light in Nov. Finally checked and hive had been robbed of most honey and most bees dead. Queen okay and small cluster left. Closed off bottom entrance and left only top entrance (1/2 moon through edge of inner cover) open. Soon front of hive covered w/brown streaks like nosema. Question: What should I do? There don't seem to be enough bees left to make it? I want to open the hive and put a boardman feeder in with Fumidil. Will the hive ever regain enough strength to protect a reduced fron entrance again? Help!
