Cockerel and Pullet Chickens: 3 Tips for Raising These Teenagers

Do you remember the glory days of seventh grade? For many people, they were filled with braces, high-water pants, and new experiences. Our teenage years are pivotal, helping shape the rest of our lives. This “teenage stage” is also important for backyard chickens – playing a key role in a bird’s future. Many families are enjoying teenage chickens this summer after buying baby chicks at spring Purina® Chick Days events and other events.  Teenage chickens are called cockerels and pullets. Chickens at this age go from cute cotton balls to pin-feathered, with new feathers and long legs.

“Backyard chickens are considered teenagers from 4 to 17 weeks of age,” says Patrick Biggs, flock nutritionist for Purina Animal Nutrition. “The teenage stage isn’t talked about much in the backyard chicken world, but it’s a very important growth phase. These weeks are a lot of fun; they’re filled with quick growth, defined personalities, and backyard exploration.”

Since exciting changes can be seen during this phase of the chicken life cycle, there are often many questions. Here are three of the most common questions received by Purina this spring about cockerel and pullet chickens — the awkward teenagers of the chicken world.


Is My Chicken a Boy (Cockerel) or a Girl (Pullet)?

As birds develop, their gender becomes much more obvious. New primary feathers develop along with new names. Pullet is the term for a teenage female, while a young male chicken is called a cockerel.

“Between 5-7 weeks, you should be able to begin visually distinguishing males from females,” Biggs explains. “Compared to pullets, the combs and wattles of cockerels often develop earlier and are usually larger. Females are typically smaller in size than males. A female’s primary flight feathers on her wings are generally longer, but the developing tail feathers of males are bigger. If you are still uncertain of gender, you’ll be sure who the males are when you hear them attempting to crow.”


When Can Chicks Go Outside to the Coop?

“Keep chicks in the brooder until week 6,” Biggs recommends. “As chicks grow in the brooder, keep birds comfortable by providing one to two square feet per bird. The temperature should be between 70 to 75 degrees Fahrenheit to help them get ready to move outside. Your chicks require less heat because they are now larger and can better regulate their body temperature.”

Transitioning birds from brooder to coop between weeks 6 and 8
1. Remove supplemental heat.
2. Move brooder into the coop.
3. Release chicks into the coop with the brooder still available for an option.
4. Supervise chicks outside of the coop in small increments.
5. Keep young chicks separate from older birds until they reach the same size.

What do Cockerel and Pullet Chickens Eat?

Many new flock raisers this spring wonder about switching feeds as birds grow. Biggs advises keeping the feeding program similar from day 1 through week 18.

“Continue feeding a complete starter-grower feed through 18 weeks of age,” he says. “Starter-grower feeds are higher in protein and lower in calcium than layer feeds. Look for a starter-grower feed with 18 percent protein and no more than 1.25 percent calcium for laying breeds. Meat birds and mixed flocks should be fed a diet containing at least 20 percent protein.”

Too much calcium can have a detrimental effect on growth, but a complete starter-grower feed has just the right balance for growing birds. The building blocks birds receive from their feed are put into growing feathers, muscle, and bone. Prebiotic and probiotics support immune and digestive health, while added marigold extract promotes brightly colored beaks and leg shanks.


“Ideally, wait until birds are 18 weeks old before introducing treats and scratch,” says Biggs. “It is important that birds receive proper nutrition in early development. If you can’t wait to spoil your birds, then wait until the flock is at least 12 weeks old. Keep the treats and scratch to a minimum – no more than 10 percent of total daily intake from treats to maintain nutritional balance.”

Biggs emphasizes that feeding growing birds is simple.

“After moving birds to the coop, continue feeding a complete starter-grower feed and complement with scratch for a treat,” he says. “Then, watch your pullets and cockerels grow and change each day.”
