Just like chickens quail make an egg laying noise as well, it’s a sort of low whistle.
Last night I came into the room just as Button started to make her noise, there was an egg behind her that I picked up, it was still warm and a little bit sticky. Then I heard a light tap noise from behind her. She’d laid another one!
I had started to think that I had got the sex of the male wrong in that cage has there is often one too many eggs for the number of hens in there. It’s amazing really when you think of how big they are that they have room for more than one egg inside them at a time, let alone two.
