They usually fly to the Family Room hutch (Rubber mat on top)... or into the living room then on top of the Doves Aviary (Screen roof over Aviary, sand floor like a litter box). see link= https://www.facebook.com/photo.php?v=10151485803695295
Sometimes they fly down the hall 3rd door on the right to my office and spend the day with me. There I have special Perches with a rubber mat (see pic), on top of a file cabinet where they like to sleep, and a special perch with tray, over the computer keyboard where they often take naps. They are never in the house unattended.
Simon Pigeon can, but rarely flies. That's why HE is able to mostly live in the house but occasionally he wants to go outside. He has a special area in the family room where he hangs out. Simon and Tuna cat sleep on my chest while I watch the TV news.
He usually spends the day with me in my office sleeping on my shoulder or the back of my desk chair, or...I've learned to type with one hand because he insists on being held and cuddled a lot.
When inside, they spend almost all the time in designated areas that are easy to maintain. They are odor free (unlike chicken poop). Not too much different than cats or dogs in the house (except for feathers instead of fur to clean up).
Often they sit in front of the door, sometimes peck on the glass (Can't reach the doorbell).
They both love to be hugged and cuddled.
