My neighbor, a kind & loving woman, recently purchased two parakeets & a cockatiel. She asked me to keep the birds with mine because her home was being fumigated & the fumes would kill the birds. My rescue birds are not caged because I believe captivity & cages violate their nature. They have cages but they just perch on them to canoodle, socialize, & poop. Most birds are social animals & grieve solidarity. Cockatiels especially demand companionship & develop severe psychological disorders without it. Her little guy sits alone in a cage all day but I couldn’t responsibly let him fly free while caring for him. My little flock are hovering around his cage & he seems overwhelmed to again meet some of his own kind. It’ll break my heart to send him home alone but I will suggest to her that getting him a companion is a must.
