When my mom was near the end of life last year I traveled to spend time with her and Gary, dh, fed and watered the flock. I covered the entire bird room floor in layers and layers of newspapers so he didn't have to sweep/mop every day. The work in defrosting, chopping and feeding was more than enough for him considering he has a huge fish keeping operation that requires much of his time. I figured worse case scenario, Rose would make a giant nest on the floor by shredding the newspapers. All went well and the newspapers were intact when I returned. Messy, but intact. It worked really well.
I knew mine could not all be caged for that long without serious cage cleaning. This allowed much of the mess to go on the floor because they spent so much of their time out of the cages. And the floor mess dried on the layers of absorbant newspaper. It was an emergency situation which worked for me. For a vacation or business trip where I had time to line out someone to clean cages, etc I would have done differently.
He did rotate out of cage time for the girls.
