WOW, Catfish, seems like you have your hands full. Sounds scary, fun, exciting all at once.I like having multiple birds, but it is difficult. Each one has to have time by themselves without another bird, so I have coordinate their time out.
Gelato the parrotlet has to have time with just the 2 of us or with another person, he does not like other birds. period. He terrorized my budgies when I let him out of his cage in my bird room... and I'm to nervous to let him out with my quaker (who also hates all other birds)
My quaker actually bit the toe off of my budgie who was in a cage... I turned my back to pick up some text books when I heard screaming and saw blood. My budgie is okay btw.
Just because you bird acts lonely doesn't mean another bird is the answer. My parrotlet snuggles with his binky, but doesn't like the idea of any bird near him. He prefers me and my partner, that's it.
