When we talk about adult Coturnix Quail they will be over six weeks of age, although they still have a little more growing to do until you see any eggs. Providing they have had good management Coturnix Quail lay eggs from around seven weeks of age, you should get an egg most days during the summer.
To start with the eggs can be super size with double yolks, or very small almost pea sized (see photo below), after a couple of weeks they usually will lay regular sized eggs.
