Each hen lays an average of 5-8 eggs each clutch. They are laid every other day and usually the incubation starts after the third or fourth eggs is laid. They need to be incubated by the mom for 18 days before they will hatch.
24 hours before they hatch you can usually hear them chirping inside the egg as they work their way out! Each baby is born blind and naked except for a few down little feathers, and needs the heat from mom to stay warm.
