Kobi is doing some strange behavior. When I let both Linnies out of the cage they fly to my recliner and play there. Now if I sit in this chair Kobi has a temper tantrum. He verbally fusses at me and will bite if near my hand or arm. I get the feeling he has taken ownership of the chair and does not want me sitting in it. Guess this is called chair possession. With most birds it's the cage but not Kobi. Should I let him have his way and not sit there when it's out of cage time?
