Okay, I have read several post here and looked in my books to see if what I am seeing is robbing and I am just not sure.
I do know I have one weaker, one stronger hive. Both were started from packages about 10 days ago. The weaker had to be shaken back to the bottom box 7 days ago when they decided to move into the feeder.
Today I go out and there is a good many more bees going back and forth in front of the weaker hive. I watched for fighting at the entrance and didn't really see it. About 1/3 of the bees going in had pollen in their baskets. Occasionally I saw a bee being carried out of the hive by a worker who flew into the air before releasing the bee. Both hives still have the smallest entrance reducer on about 1".
I tried a couple of suggestions on this board to prevent/stop robbing. A small amount of Vick's rub in front of the entrance. I also opened up the stronger hive, removed the top and inner covers. This seemed to help, but not stop all of what was going on.
I have carniolan queens. I know carniolans are suppose to not be as bad as other races about robbing. However, the packages looked to be of mixed origin. I don't know if this will have anything to do with it.
Any suggestions would be greatly appreciated.
