I just got two cockatiels today. I was planning to get only get one. When I got to the ladies house she had a second tiel with very little feathers. She asked if I wanted to take him too, she said they would be lonely with out each other. She said that the feathers fell out because he is old but she did not know how old. Both seems to be plucking feathers out. So I am wondering if there might be more to her story. What other reason would cause my tiels feathers to fall out? What could I try to get them to grow back. I know she said that he eats mostly people food and not bird food. Is that healthy? I do not plan to keep that up. Any advice would be great.
