I got a rescued amazon 7years old. He allows head scritches but bites ur hand after awhile and keeps chewing it like food. He loves food. I think he thinks anything that goes in the cage is food. He doesnt step up. Previous owner didnt train him. He talks a little. He doesnt talk when he sees you. Is he shy or what? Is it too late to teach him to step up? and other tricks? Does any one have any suggestions on how to go about training? Also how could i get him to talk more and be less shy?
