I have a male light green spangle that call Fatty! He always ends up being everyone's favorite because he is such a character. His real name is Basil, but I started calling him Fatty and it stuck. He is fat. He was a rescue but I got him on a healthier diet and he lost some. He can't fly because he has some genetic condition that makes his feathers kind of messed up. So that may be a factor in his chubadaubness.
