Hello....my 3yo male budgie just lost his companion (parrotlet), and of course, there has been a bit of a behavior change. He is spending a lot more time by choice in his cage. He and my pionus have cages next to each other, but they seem fairly neutral towards each other, e.g. they look at each other, occasionally hop on/off each other's cage, but otherwise don't interact. My pi is very mellow, and more of a perch potato. I'm considering a cockatiel to join him and share a large flight cage, but again, the cages or open most of the day. I'm also considering another budgie if I can find a hand tame rehome/adoptee. Does anyone here have experience with such an arrangement? I would be rehoming/adopting, not buying from a breeder. Thanks for any input.
