Does egg laying make them noisy?

Forgive me if this is a stupid question, but it's all such a new world and the books I've got aren't that great but you folks are wonderful at helping.  This is day two of egg laying.  I think it's only my Black Star who is laying and she has suddenly taken to making an almightily racket for about an hour, then when I go in there's an egg.  Is this normal and will she (all of them) do this for ever because 6.30am isn't lovely for me (they're under my bedroom window) or the neighbours I imagine!

Oh she's out and about when she does it and it is a BOK BOK BOK BOOOOOKKKKK but for an hour before she laid the egg.  Maybe it's because it's new for  her too!  I only hope she quietens down and the others don't follow suit because it's not restful for anyone.

Oh yes some are very noisy probably saying something along the following:-
I want to lay an egg!!,
Oh look at me I've laid an egg!!,
I'm doing my job of egg laying why aren't you?
My eggs sat there waiting for a broody hen to go sit!
I'm just kidding so I can watch the human come running, Oh what fun 
When she comes running gals trip her over 

in which case she is bragging and saying number 3 in the list!!
