A herding dog’s worse nightmare

Poor Blue is going crazy trying to figure out how to herd me, Blondie, the three birdcages downstairs and the two birdcages upstairs into the same general area so she can sleep soundly, knowing her job is done.  How do I tell her that even I can’t carry those cages up the stairs for her?  I’m hoping she’ll eventually figure out that the birds are already in safe “pens” for the night and she can relax.
