Since I posted I've been reading other robbing questions. I don't have a robber screen. The hive still is full of bees and honey, I took a quick look in today. Yesterday I did a complete look at the hive and it was doing great. I realize now that I am the cause of them being robbed
Yesterday I took the empty top feeder off this hive and just set it off to the side and left it since it was full of bees. I was going to get it in a day or 2. I'm thinking now - WRONG THING TO DO!! It must have attracted the robbers even though it was empty. Hopefully I've sealed the entrance off early enough that they can defend themselves.
