Hello again,
The way you can tell how old he is (up to the age of 3-ish) is by his back/train feathers.
Your boy still seems to have only barred (=black and white "striped") feathers on his back.
By the time he turns 2, he will be getting some green feathers and eye feathers (why I said he was 1+).
If you want a more accurate idea about his age, you could post a clear picture of his whole back.
You seem to have a lot of pea questions!
Have you taken a look at the Peafowl Stickies?
They are full of all kinds of useful pea information:
No need to apologize! Everyone has questions!
The stickies are sometimes just a good place to find a lot of answers at once.
But we peapeople are always happy to answer questions too!
And we are always happy to see more pictures of beautiful birds like your new friends.
