I don't have a good photo of it, so please bear with my explanation
Chip will sometimes nap laying on the bottom of his cage flat on his tummy and chest, face down. First, before anyone gets concerned, I have heard of this behavior before in some other budgies, which is the only reason I'm not completely freaking out. If you saw this, trust me it looks quite 'alarming' to say the least. You can imagine!
The first time I saw this I thought the worst!
I think this is more common in the English budgies, and more common when they're younger maybe? Mink never did it, and I've never had any other species of bird do this behavior.
I know he's okay, and he is being completely normal otherwise. When you call his name or go up to him when he's laying there like that, he will respond by turning his head to look at you. He is completely alert, and is not lethargic, he can just get up, stretch his wings and run to his food or a toy a second later
