How long do chicks need a heat lamp?

So you’ve decided to raise baby chicks and have everything set up for their arrival: the brooder, the feeder, the waterer, and the all-important heat lamp. But now that those fluffy little feathered babies are chirping away in their new home, how long do they need that heat lamp? You don’t want them to get too cold, but you also don’t want them to overheat. The short answer is that most chicks need a heat lamp for the first 3 to 4 weeks of life as they develop feathers to keep themselves warm. But a few factors must be considered to ensure your chicks stay happy and healthy during those critical early weeks. Please keep reading to learn how long you should keep that heat lamp on and when it’s safe to turn it off. Raising chicks is rewarding work, so let’s ensure you give those little peepers the best start in life.

Why Chicks Need Supplemental Heat

Chicks can’t regulate their body temperature for the first few weeks of life, so they need extra help to stay warm. That’s where the trusty heat lamp comes in.

For the first week of a chick’s life, the temperature should be around 95°F. You’ll want to place the heat lamp about 18–24 inches above the chicks so they can move closer or farther away to regulate their temperature. Check on your chicks frequently to make sure they seem alert and active. They’re too cold if they’re huddling together directly under the lamp. If they’re spread out and panting, they’re too hot.

Adjusting the Temperature

After the first week, you can lower the temperature by about 5 degrees per week. So in week two, aim for 90°F; in week three, 85°F, and so on. When your chicks are fully feathered, around 4-6 weeks old, they should be able to tolerate temperatures as low as 70°F. At this point, you can turn off the heat lamp completely.

Other Considerations

Make sure to place the heat lamp securely to avoid a fire risk. Please don’t leave it on when you’re not home or sleeping. You should also provide multiple small feeders and waterers at different levels so even tiny chicks can eat and drink quickly. Place them on opposite ends of the brooder to encourage exercise.

Raising chicks is rewarding but requires effort and diligence, especially in those early weeks. With the proper supplemental heat and adjustments over time, your little flock will thrive and be ready to venture out to the coop in no time!

How to Know if Your Chicks Are Too Hot or Too Cold

So your chicks have arrived, and you’ve got the heat lamp set up, but how do you know if they’re too hot or cold? Monitoring your chicks carefully during their first few weeks is essential to ensure they stay healthy and comfortable.

Check on your chicks frequently, especially for the first 3–5 days. Their behavior and environment will tell you a lot about whether the temperature is right. If the chicks huddle under the heat lamp, they’re probably too cold. You’ll want to lower the light or use a higher-wattage bulb.

On the other hand, if the chicks are spread out around the brooder and panting, they’re too warm. Raise the heat lamp higher or switch to a lower-wattage bulb. Comfortable chicks will act normally – eating, drinking, and moving around.

Placing your hand in the brooder is an easy way to gauge the temperature. It should feel warm but not hot. Watch out for chicks peeping loudly, indicating they’re too cold or hot. Check that all parts of the brooder are evenly heated since chicks may crowd in warmer spots.

Once chicks are 3-5 days old, you can start raising the heat lamp little by little so they can adjust to the temperature outside the brooder. Chicks usually only need supplemental heat for 2-6 weeks before they develop enough feathers to self-regulate their body temperature.

Providing the right temperature during those critical early weeks will help your chicks grow healthy and strong. With frequent monitoring and minor adjustments, you’ll have the hang of it and can enjoy watching your little flock thrive!

Newly hatched chicks need an external heat source to keep them warm until they develop feathers and can regulate their body temperature. For most chicks, a heat lamp must be used for 2 to 6 weeks. The exact time will depend on the breed of chick and the environment.

When to Remove the Heat Lamp

You’ll know your chicks are ready to do without the heat lamp when:

  • They are fully feathered. Most chicks will be fully feathered around 4 to 6 weeks of age. Feathers provide insulation to help keep chicks warm.
  • They can huddle together. Chicks will huddle together for warmth if they feel chilled. It indicates they are warm enough if they spread out in the brooder instead of huddling.
  • They are active and eating normally. Chicks that seem alert, active, and have a good appetite are not bothered by cooler temperatures and are likely ready for the heat lamp to be removed.
  • The ambient temperature is warm enough. The area where the chicks are housed should be a minimum of 70 to 75°F for the heat lamp to be removed. Monitor the temperature to make sure chicks remain comfortable.
  • There are no signs of chill. Look for chicks fluffing up their feathers, huddling, shivering, or peeping loudly, indicating they are too cold without the added warmth from the heat lamp.
  • Consider the chick’s age and breed. Larger breeds may need the heat lamp longer, up to 6 weeks. Smaller breeds are often ready around four weeks. But let the chick’s development and actions guide you.

When you remove the heat lamp, gradually raise it higher over a few days. This allows chicks to get used to the cooler temperatures slowly. Closely supervise your chicks to ensure they remain healthy and comfortable without the added heat. If at any time they show signs of chill, you may need to return the heat lamp for a few more days.

When It’s Safe to Turn Off the Heat Lamp

Once your chicks have grown most of their feathers and move around independently, they are ready to survive without the heat lamp. Usually, about 3 to 4 weeks of age, chicks can self-regulate their body temperature. Some signs your chicks are ready to turn off the heat include:

  • They are feathered: Chicks will have most of their feathers, especially on their back and belly. Only a tiny amount of down will be visible. Feathers provide insulation to keep chicks warm.
  • They huddle less: Chicks still require heat and will huddle under the lamp. They stay warm if they are spread out in the brooder and not huddled together.
  • They are eating and drinking independently: Chicks that can consume food and water without assistance from the heat lamp are mature enough to generate body heat. Eating boosts their metabolism and helps with temperature regulation.
  • The brooder temperature is stable: If the temperature in the brooder away from the heat lamp remains steady. In the ideal range for chicks, you can turn off the lamp. The chicks can maintain the temperature themselves.
  • They are very active: Chicks running, flapping their wings, and jumping in the brooder do not require supplemental heat. Their activity and movement generate body heat.
  • No signs of distress: Watch chicks closely after turning off the heat lamp. They do not require the heat lamp if they seem comfortable and content and continue to eat, drink, and be active. Signs of distress like huddling, chirping loudly, or lethargy indicate they still need external heat.

With the heat lamp off, continue providing chicks with food, water, bedding, and other essentials. Keep an eye on them to ensure they’re happy and healthy in their newfound independence. In no time, your little chicks will be grown up and ready to move on to bigger adventures outside the brooder!

FAQs: Common Questions About Heat Lamps for Chicks

One of the most common questions new chick owners have is how long chicks need a heat lamp. The short answer is 2 to 6 weeks, depending on the age and breed of your chicks. Here are some guidelines to help determine when your chicks are ready to survive without the added warmth.


Very young chicks (under two weeks old) require constant warmth from a heat lamp. Their bodies are still developing the ability to thermoregulate, so they rely entirely on external heat sources. At around 2 to 3 weeks, chicks grow in feathers and gain better control over their body temperature. You can start reducing the brooder’s temperature by a few degrees daily.


Chicks need to be fully feathered before the heat lamp is removed. Most chicks will be well-feathered around 4 to 6 weeks of age. Gently pet your chicks to feel for feather growth—they should feel soft and fluffy, not bare. Chicks with full, downy feathers and the start of wing feathers are usually ready for the heat lamp to be removed.


Pay attention to how your chicks are behaving. If they are huddling together constantly under the heat lamp, they are likely still too cold without it. But suppose they are venturing further from the light, exploring their surroundings, and interacting with each other. In that case, their body temperature regulation has kicked in, and the extra heat may not be needed.


The breed of your chicks also determines how long they need supplemental heat. Smaller species develop faster, while larger breeds take longer. Generally, bantam chicks only need a heat lamp for 2 to 4 weeks, while chicks of heavy breeds like Brahmas or Cochins require 4 to 6 weeks.

When the heat lamp is removed, please continue monitoring your chicks to ensure they seem alert, active and usually eat and drink. Their comfort and well-being should be your top priority during those first few weeks of life. With attentive care and following these guidelines, you can determine when your chicks can brave the world without their trusty heat lamp.


So there you have it, the basics on how long chicks need a heat lamp. By closely monitoring your little feathered friends and ensuring they stay warm and fed, you’ll be well on your way to raising happy, healthy chickens. Once those fluffy little chicks start feathering out, lose the lamp and get ready to move them into the coop. Before you know it, you’ll collect fresh eggs from your backyard flock. Raising chickens is extremely rewarding; remember to give them the care and attention they need, especially when they’re little. The extra effort in those early days will pay off down the road. Best of luck and happy chick-raising!
