He's so precious, the pictures don't do him justice. He's a lot lighter than Sage- both his hue of green and his wings, so I'm guessing he's some different mutation to her.
He's not a strong flier at all so I think he's gone from nestbox to cage, to the pet shop rather quickly.
He's possibly the youngest budgie I've had. Sadie was pretty young as well, but she was a strong flier when I got her- her pet shop had a big aviary for the birds so she got the chance to fly about more.
