The meaning of a peep

[LocoPollo]

I am just curious what does it mean when the chick is peeping? It seems to me that to be able to peep, the chick must be breathing air, so does it mean the chick has broken the membrane when it starts peeping?

I don't know, but that is a really interesting question! (One that deserves to be at the top of the list

)

Yep, it has broken into the air cell.

Cool, Thanks!
