I opened Nuc #1 today to check on the hive beetle situation. Didn't see many so I left everything alone. I also looked in Nuc #2 and Hive #5 just to make sure they had plenty of food and also the hive beetle situation in each of those hives. They were okay.
Did not check #4 and Swarm '09 - cannot pick up or even think about lifting either of these hives so I'm sure they have plenty of food for the winter. Actually, I couldn't pick up the other hives either.
In checking my hives before winter sets in, I try to lift the back of the hive - if you can lift the hive - check the hive and start feeding immediately, they will not last the winter. If you can't lift the hive body, you should be okay. But again, it's always a good idea to open the hive and then you can tell what's happening.
