The Glow-Up: From Fluffy Chick to Egg-Laying Hen

Eggs might feel like a normal part of life, but the journey from fluffy chick to egg-laying hen is actually pretty amazing. It all starts before a chick even hatches. Inside the egg, a tiny embryo grows and develops over about 21 days. Once she hatches, that chick spends the next several months growing, feathering out, and slowly maturing into what’s called a pullet—basically a teenage hen in training.

Around 5–6 months old, something magical happens: her body flips the switch and egg production begins. Hormones kick in, her reproductive system fully develops, and she starts releasing yolks. As each yolk travels through her body, it gets wrapped in egg white, membranes, and finally a shell. About 26 +/- hours later, out pops an egg, like clockwork (most of the time).

Of course, not every hen lays the same. Good food, clean water, plenty of daylight, low stress, and a comfy coop all play a huge role in how well hens lay. Breed, age, and health matter too. But when everything lines up, it’s pretty incredible to think that your breakfast started as a tiny yolk inside a growing pullet. Just another reason chickens are way cooler than they get credit for.
