How do you look at the age

The age of the 好 is very good to judge. Just look at its paws. The old bird's paws have many epithelium, so there are often fish -like folds.If it is a relatively young bird, the color of its paws will be more bright and will not be white.In addition, it can also look at its feathers. The color of the black feathers when I was young is also relatively bright. If it is a bird, the color will be much dull, and the difference is obvious.
