I got a Blue and Gold Macaw recently, and I don't know it's age. The previous owner had it for about 3 years, but he also doesn't know the age. He wasn't very well taken care of, his feathers are a little patchy in areas, especially under the wings, its hands are grey and smooth, he has a longish-black beak with, what seems like, chips on the upper part of the beak. His eyes are white, with a light brown iris. I don't know its gender either. (I do know I put he a bit.) Also, with my cousin, it lets him pet it and he gets on his arm, but with me, when I try and pet him, he acts like he's going to bite me, and he only steps onto my arm if he was already on my cousins arm. Does he not like me? Someone please help. Thank you!
