I use a kids play pen with the fine mesh, sides fold down for easy access. I keep 2 playpens and switch out when one need to be washed down. The fine mesh will catch 99% of the mutes. I find mine at yard sales and have never paid more than $15.00 for one. I have used the play pens for 40 + years. I place them in the middle of the room that way I can walk all around them. Large bath pan as a nest box. once they start jumping up on the sides I lay out tarps to catch mutes. When they refuse to stay in the pen I tie them to a floor perch again with tarps. Tarps can be washed daily while the eyas is weathering.

Use lots of air freshener!
