I got my blue parakeet about 6 months ago, and we have gotten along pretty well. Sometimes he explores my room and he will sit on my finger, shoulder or head, but, since I’ve gotten him, he has continuously biting me. It’s got to the point where I won’t be able to hang out with him because as soon ad I get near him, he will try to bite me. When I looked up solutions, I found that you can try to shake the perch a little bit so that he will learn to associate him biting with that feeling, but it hasn’t worked at all. What can I do to teach him not to bite?
