After having birds for 19 years you just know when something is wrong. My new parakeet, Piccolo, is depressed. I have other parakeets but in different rooms. Two boys in one room who are together and a young male and female in another room together. Piccolo is by himself with my Cockatiel next to him they are like five inches away and my Zebra finch also near them. My parakeet eats, drinks, tweets in the morning but then quietly stops. He talks to the other parakeets in the other rooms when they talk and they all respond to another. Though I work and got to school. I leave the radio on for him. I have had him now two weeks and I see he is in depression. At Petco he was by himself and seperated himself from the other keets. So after I bought him and after a few days I took him out with the other keets and he hung out with them and then seperated himself again but he loves talking with them. He LOVES to come out of the cage when I let him out. He has a big cage with lots and lots of toys. I really don't want to get another parakeet?! But he sits in the corner by himself talks to himself sometimes. I just don't want to get another parakeet. Piccolo is something special. He is unique. And he is still very shy of me. He allows me to scratch his head, touch his belly, allows me to grab him, and he lets me kiss him on the head and beak. Usually after getting new parakeets they bite. And when he sits on top of his cage and I approach him he runs underneath his blanket that covers his cage and peaks out his head to see where I went. I do love him but I don't know what to do? He likes other parakeets but he bit one of the males that went by his cage. He likes my tiel and hangs out with him but he loves my Zebra Finch? He is very observant on what I do. So how can I make him happy? He seems like he is in depression but other times he isn't and I don't want to get another parakeet. I am very very picky on getting birds. So what should I do?
