The_christmas_chicken

Have you guys seen a guy named the_christmas_chicken? He flys around, usually in spawn, dropping gold blocks named "from the_christmas_chicken" and other goodies, and takes gift requests. He also asks for "naughty/nice" reports, and anyone with a witness saying they were nice might get a diamond (named "You've been good!" Or maybe even a diamond block (named "You've been really good!"

So anyway, have you seen him? And what do you think about him?

... And who do you think he is?
