I have some friends who have a peahen that lives in the house as a pet. When you sit down she will come and put her head on your leg to be stroked, then happily doze off. Her name is Shreep, which is the sound she makes when you're not fixing her food fast enough. She has and indoor cage and goes into it when she wants to poo and sleep. She's amazing. They have 5 other males and females in an outdoor pen that is about 20 x 20. I think Shreep is the exception and was imprinted at birth on humans. Generally Peafowl and other birds are flock animals and need the safety, security and companionship of others of their kind. So if you want mentally well adjusted birds, get two or more. I would get three so that two of them could talk about the third one behind his back. HA!
