I installed bees on Tuesday, checked Thursday and all queens were released. I have entrance reduced down to 3/4x1". My question is when should the opening be opened up, and should it be opened all the way or partially? They seem to be bottlenecked at the entrance coming and going. Also I have screen bottom boards. I have them closed up right now, until they get more comfortable with their new home. When would be long enough if a wait to open it up?
