A couple weeks ago i bought a 3 yr old quaker parrot with his cage and all off of craigslist. Every time you put your hands near him, even just on the bars of his cage he freaks out, lunges at my hand and it sounds almost like he hisses? Is he doing this because he just needs more time to get used to me? Or is it because he was never really hand tamed to begin with? What should i do to get him to trust me? Hes such a pretty bird and hes so sweet if you dont try to put you hands near him ): does anyone know how to stop the biting? Thanks.
