On Sat I checked on my hive, both deeps were about 95% full of brood & food, so I added a queen excluder, a spacer with an entrance hole, and a medium super for honey. On Sun morning, the whole front of the hive was covered with bees. I went to check, they were all furiously buzzing with thier stingers in the air, and thier heads down.
Now, I have only been a beekeeper for 3 months, so I have no idea what this might mean. There are a few varmints around, they keep stealing the ant traps, but it was also a humid morning. I went to get my camera to get a picture, but they had cleared. I had noticed a few going into the entrance hole in the spacer for the top super, and others coming and going from the bottom entrance. I checked during the day, activity seemed normal, just not as much as usual. I have no idea how long they were covering the hive, & it was a humid day.
I do use a screened bottom board, and there are two entrance holes in a spacer above the inner cover for ventilation, and it was only about 88 yesterday.
I'm hoping they didn't swarm, but there is less activity then normal. It's raining this morning, so I am going to try to get into the hive this afternoon to check if they are all still there.
Any helpful ideas as to thier covering the hive in that manner?
