I live in a two-story house with an open floor plan. The birds currently have their own room on the second floor that is also my work-from-home office, and is where they primarily spend their time. We have an upstairs game room area that also connects to the downstairs living areas via a doorway/stairs and a pass-through internal "window" that I'd like to have them out in more, but I need a way to close off these two entry points to keep them upstairs. Does anyone have any suggestions for non-permanent ways to do this? Our current thought for the pass-through is a secured curtain, but we are stumped on the doorway from the stairs.
