I am probably reading this wrong, but you have a screen top on the box, and bad weather on the way. And you can't get back to them until Tuesday. If this is the case, they will be caged in a box with a screen roof. As for as seeing the queen, I don't worry about that. If you get the queen in the container the rest will follow her in shortly. If she isn't in there they will go to where she is. It won't take a long time to tell if she is there. Good luck to you and your bees
