hi, my african grey congo keeps screaming and flapping his wings, at the same time, but his wings are clipped. This happens randomly and i dont really know what it is. Some times i just give him food and he quiets down, but this doesnt always work. Some times the screaming is screaching, and sometimes is just noises, like he clicks 2 times the goes ooooh. My african grey is 8 months old. please help, thanks
