I combined two hives this afternoon. One of the hives is weaker, it has no queen and had 10-15 queen cells (I removed these). The Strong hive is on the bottom with a marked queen that I observed before closing it up. There is newspaper between the two hives with perforations. The bees should eat through the newspaper over the next 3 days and will be one big happy family since they will both be accustom to each other's smell. My mom, who is an experienced ex-beekeeper, confirmed that she's done this in the past and it works like a charm.
I watched a bunch of Youtube videos, read some how-to's online and did it by the book. Please see attached image.
The how-to's I read said not to leave an opening in the weak hive's deep. For example, if an inner cover is used, it said not to put the notch side towards the weak hive where the bees could leave. Note, I didn't use an inner cover, but I'm feeding the weak hive.
My concern is heat. Tomorrow will be 95 degrees F and there's no ventilation for the weak hive at all. Did I just build a cruel death box for these poor bees or is it OK? If it is a problem, how do I create ventilation for the weak hive?
