I guess I need to be told when to cover them up

So during the night both Inca and Sage sleep on separate swings. They wont share their  sleeping areas.  When they wake up I switch the swings out for their two favorite toys. They wont use the swings during the day at all. So got home last night from work around 930 pm and both were hanging side by side on the cage side just looking at me. All I got which seemed like them saying " Excuse me where have you been ? Its time for us to go to sleep , put our swings up now."
