Is "The Egg Song" a real song?

[GLBRWyans]

My ladies started laying about a months ago , mind you I am new at this , but every time I here the song there is an egg . My wife swears against it . lol

Song? No. A bunch of squawking and cackling? Yes! But it is, indeed, music to my ears to get that egg!

That's kind of why I was hoping the "egg song" would tip me off, if it happens while they are free-ranging.

Mine don't start singing until they are off the nest and have had a nibble and/or a sip. Sometimes a delay of 2-3 mins.​
