Odd beak thing (flexi beak)

[Quail lady]

Does anyone else have quails who do this strange beak stretch? I'm not alarmed, just think it's adorable and a bit odd...

I can't really tell from the picture, is the beak a normal shape? It's just kind of akin to a yawn or grinding teeth but for a bird?
I've never seen my own do that, but that's not to say it doesn't happen when I'm not looking.

Cheers,
Jessie

It looks like a beak yawn too me.
