Hello everyone, I have a 2 year old Congo named Shaggy. Lately when I hold him he shakes, puffs up his feathers, pinpoints, and make a strange noise that I really can't explain, maybe I can get it on video though. I was just wondering if this is a normal thing for a Grey to do or if he's overstimulated or something else. Thank you for your help and if this is in the wrong place I'm sorry.
