I just recently rescued a green wing that was living in a dog cage that was covered in feces. I got him out and had him bathed, and nails and beak clipped, his feet are slightly deformed so he cant stand on a perch. I have never had a bird before and he is pretty aggressive, how long does it normally take before i can pet him, he lets me rub his beak but thats it. Is there anything i can do to help him cope with a new life with people that will love him. He seems to be eating good and will take oranges and grapes from my hand. how do i get him out of the cage so i can clean it. PLEASE HELP i love him already and dont want to have to give him to a rescue. Any and all advice will be greatly appreciated
