A chicken takes about 24–26 hours to form and lay a complete egg under normal conditions.

Quick Scoop

  • Most hens need roughly one day to make and lay a single egg.
  • The longest part of the process is building the shell, which alone takes around 20–21 hours.
  • After laying, it usually takes 15–30 minutes before the next egg-forming cycle starts, so practical laying frequency is about one egg almost every day at peak.

Tiny timeline inside the hen

  • Yolk release from the ovary: about 30 minutes.
  • Egg white and shape formation in the oviduct: roughly 1–2 hours.
  • Shell formation in the uterus: about 20–21 hours.

In backyard or farm conditions, this means a healthy laying hen on a good light schedule (around 14–16 hours of light per day) can produce close to one egg per day during her best laying years.
