Expect first eggs between 18 and 24 weeks of age

Most standard chicken breeds begin laying between 18 and 24 weeks (4.5 to 6 months) of age. The first eggs are typically small — sometimes called "pullet eggs" — and may have irregular shapes, soft shells, or double yolks as the reproductive system calibrates. Egg size gradually increases over the first 6–8 weeks of laying until reaching full size.

Why It Works

This 18–24 week range represents the age at which the hen's reproductive system reaches sexual maturity and can produce eggs. The ovary begins releasing yolks (ovulation), which travel through the oviduct where albumen, membranes, and shell are added over roughly 25 hours. The exact timing within this range depends on breed, nutrition, daylight exposure, and overall health.

Tips

• Production breeds like Leghorns and Golden Comets often start at 16–18 weeks
• Heritage and dual-purpose breeds like Orpingtons may take 24–28 weeks
• First eggs are often laid on the coop floor rather than in nesting boxes — place fake eggs in boxes to guide behavior
• Do not rush laying with supplemental light before 18 weeks — let the reproductive system develop fully
