I had a robbing episode occurr during my hive inspections last week. This plus unseasonably cold weather on the way caused me to feed the weak hive and put entrance reducers on all 3 of my hives (3 inch opening). The next few days are going back up into the 90's.
Should I remove the reducer from all hives or continue to leave it on the weak one? I was going to pull from the strong hives tonight but lots of bees out on the entrance.
