What to Do If Your Egg Incubator Loses Power

How to Protect a Hatch During a Power Outage

Power outages have terrible timing.

They show up during storms.
During ice events.
Or mysteriously at 2 a.m. when nothing else in the house seems to be running.

And somehow they love to show up right in the middle of an incubation cycle.

You walk past the incubator and notice the display is dark.

Your stomach drops.

You stare at it for a moment hoping maybe… just maybe… the screen is just sleeping.

It isn’t.

If you're incubating eggs at home when the electricity suddenly goes out, it can feel like weeks of waiting just disappeared.

But take a breath.

Most incubating eggs can survive a short power outage — and sometimes even longer — if you respond the right way.

Eggs are tougher than people realize.

After all, a broody hen doesn’t sit perfectly still on the nest like a tiny feathered statue. She gets up to eat, drink, stretch, and occasionally yell at another chicken who walked too close to the nest box.

During those breaks, the eggs cool slightly before she returns.

That means a temporary temperature drop doesn't automatically ruin a hatch.

The goal is simple: hold onto as much heat as possible until the power comes back.

Emergency Checklist: Incubator Lost Power

When the incubator suddenly shuts off, panic is a normal reaction.

Before unplugging random things or personally blaming the power company… start here.

Immediate Steps

1. Do not open the incubator
2. Leave the eggs inside to retain heat
3. Wrap the incubator with towels or blankets
4. Move it to the warmest room available
5. Add warm water bottles if the outage continues

The biggest mistake people make is opening the incubator to “check the eggs.”

Every time the lid opens, warm air escapes. Right now the incubator is doing its best impression of a thermos.

Let it.

Does the Hatch Stage Matter During a Power Outage?

Yes — embryos respond differently depending on how far along incubation has progressed.

During the Incubation Stage (Days 1–17 for Chickens)

During most of incubation, embryos are forming organs, bones, and circulatory systems.

If temperatures drop during this stage, development usually slows rather than stopping completely.

Think of it like pressing pause on a movie. Once temperatures return to normal, development continues.

Nature designed eggs to tolerate short cooling periods because broody hens occasionally leave the nest.

They grab a snack.
They drink some water.
They yell at another chicken.

And then they return to warm the eggs again.

For many hatches, the only noticeable effect of a temporary outage is that chicks hatch a little later than planned.

During Lockdown (Last 2–3 Days Before Hatch)

Lockdown is when things get serious.

For chickens, lockdown typically begins around day 18.

• Eggs stop turning
• Humidity increases
• Chicks position themselves to hatch

Short outages can still be survivable, but restoring heat becomes more important during this stage.

If Chicks Are Already Pipping

If chicks have started pipping when the power goes out, the situation can feel dramatic.

This is when people most want to open the incubator.

Try not to.

Opening the incubator releases both heat and humidity, which chicks rely on to finish hatching.

Once temperatures stabilize again, many chicks continue the hatch normally.

Chicks are stubborn like that.

How Long Can Eggs Survive Without Power?

Egg embryos are surprisingly resilient.

Because broody hens occasionally leave the nest, eggs naturally experience small temperature drops in nature.

Sometimes the hatch simply runs a day or two late rather than failing completely.

How Temperature Drops Can Delay a Hatch

When incubation temperatures drop, embryo metabolism slows.

Development pauses until warmth returns. Once temperatures recover, development continues — but embryos may need extra time to finish growing.

Which Eggs Handle Power Outages Best?

Not all eggs respond the same way to cooling.

Egg size and shell thickness make a difference.

Small eggs cool quickly.

Large eggs act like tiny thermal batteries.

Real Homesteader Tricks to Save a Hatch

When power stays out longer than expected, poultry keepers tend to get creative.

These tricks may not look fancy…

But they’ve saved plenty of hatches.

Add Thermal Mass

Place sealed bottles of warm water inside the incubator.

Water stores heat extremely well and slows temperature changes.

Wrap the Incubator

Use towels or blankets to slow heat loss.

Think of it as putting a winter coat on it.

Place the Incubator Inside a Cooler

A cooler acts like a giant insulated chamber.

It may not win design awards.

But it works.

Warm the Room Instead of the Eggs

If possible, move the incubator into the warmest room in the house.

Warming the whole space is much safer than blasting the eggs directly with a heat source.

Do Some Incubators Handle Power Outages Better?

Yes.

Some incubators retain heat better than others.

Helpful design features include:

• thicker walls
• foam insulation
• double-wall construction
• cabinet-style designs

Larger incubators also hold heat longer because they contain more thermal mass.

Eggs themselves hold heat.

Late in incubation, embryos even produce small amounts of metabolic warmth.

Some incubators also offer dual-power capability, meaning they can run on both household power and a 12-volt battery. That can make a big difference during longer outages.

Should You Use a Generator?

Yes — generators can be extremely helpful during longer outages.

Most incubators only use 30–120 watts, meaning even small generators can power them easily.

Use a Surge Protector With Every Incubator

A surge protector is strongly recommended.

Power surges often occur when electricity returns after an outage.

Those spikes can damage thermostats and control boards.

A surge protector adds an extra layer of protection.

Avoid Power Surges With Generators

When using a generator:

1. Start the generator first
2. Let it stabilize
3. Then plug in the incubator

This helps prevent voltage spikes.

Always Run Generators Outdoors

Generators produce carbon monoxide.

Never run them inside homes, garages, or barns.

Always operate generators outside and away from buildings.

What Temperature Is Too Cold for Incubating Eggs?

Normal incubation temperature is about 99.5°F.

Embryos can tolerate short drops, but extreme cold becomes dangerous.

Signs an Egg May Have Stopped Developing

After a power outage, candling eggs can reveal whether development continued.

Signs Eggs Are Still Developing

• visible veins
• embryo movement
• expanding dark embryo mass

Signs Development Stopped

• clear egg
• blood ring
• no changes over several days

If unsure, continue incubating several extra days.

Eggs sometimes surprise people.

Incubator Power Outage FAQ

Will eggs survive if the incubator turns off?

In many cases, yes. Fertile eggs can tolerate short temperature drops because this naturally happens when a broody hen leaves the nest to eat or drink.

If the incubator stays closed and retains heat, embryos can often survive outages lasting several hours. The most important thing is conserving the heat already inside the incubator and restoring normal temperatures as soon as power returns.

Many hatchers are surprised to find their hatch still succeeds even after a temporary outage.

How long can eggs survive without heat?

Short outages under 1–2 hours usually have very little impact on developing embryos.

If temperatures drop for several hours, development may slow down and the hatch may occur later than expected. Longer outages increase the risk of embryo loss, but eggs sometimes recover even after extended cooling.

Large eggs like duck or goose eggs generally retain heat longer than smaller eggs like quail eggs.

Will a power outage delay my hatch?

Yes, it often can.

When temperatures drop during incubation, embryo metabolism slows down. Development pauses until warmth returns. Once proper temperatures are restored, development continues — but embryos may need extra time to finish growing.

Because of this, many hatches occur one or two days later than expected after a significant temperature drop.

If your incubator lost power, it’s usually best to give the eggs several extra days before assuming the hatch has failed.

Should I restart incubation after a power outage?

No. Incubation should continue normally once temperatures return to the correct range.

Embryos often pause development during temperature drops and resume once conditions stabilize. Restarting the incubation process or discarding eggs too early can cause unnecessary loss.

Instead, continue incubating and monitor development by candling the eggs.

Should I open the incubator to check the eggs?

It’s best not to.

Opening the incubator allows heat to escape, which can cause temperatures to drop faster during an outage. The incubator itself helps retain warmth, especially if the lid remains closed.

Keeping the incubator closed helps preserve the heat already inside.

Can chicks still hatch if the incubator cools down?

Yes, it’s possible.

Eggs are often more resilient than people expect. Many hatchers have successfully hatched chicks after temporary power outages. The hatch may simply occur later than planned.

If temperatures were restored within several hours, there is still a good chance the embryos continued developing.

Patience during the final days of incubation can make a big difference.

What is the best backup plan for incubators?

If you live in an area where power outages happen occasionally, having a backup plan can protect future hatches.

Common options include:

• a surge protector to protect incubator electronics
• a portable power station
• a small generator
• extra insulation for the incubator

Most incubators use relatively little electricity, so even a small backup power source can keep them running until the power returns.

Common Mistakes Hatchers Make During a Power Outage

When the incubator suddenly shuts off, it’s easy to react quickly — and sometimes those quick reactions can actually make things worse.

Here are a few mistakes experienced hatchers learn to avoid.

Opening the Incubator Repeatedly

This is by far the most common mistake.

Every time the incubator is opened, warm air escapes and the temperature drops faster. The incubator can usually hold heat for a while if left closed, so resist the urge to keep checking on the eggs.

Let the incubator hold onto the heat it already has.

Trying to Heat the Eggs Directly

It might be tempting to aim a heat lamp, hair dryer, or heating pad directly at the eggs.

This can actually cause uneven heating, which is harder on embryos than a gradual temperature drop.

Slow, stable warming is much safer than sudden bursts of heat.

Moving the Eggs Too Much

During an outage, the best place for the eggs is usually right where they already are.

Constantly moving eggs between locations can cause unnecessary temperature swings and increase the chance of damage.

Focus on stabilizing the incubator environment instead.

Assuming the Hatch Is Ruined

Many people assume the worst as soon as the incubator cools down.

But eggs often recover once the proper temperature returns.

Some hatchers are surprised to see chicks emerge from eggs they thought were lost. The hatch may simply happen later than expected.

Patience can make a big difference.

Forgetting to Plan for the Next Outage

One unexpected outage is usually enough to convince most hatchers to prepare for the next one.

Simple backup plans can help protect future hatches:

• a surge protector
• a portable power station
• a small generator
• extra insulation for the incubator

Having a backup plan in place means the next outage will feel a lot less stressful.

Final Thoughts

Losing power during incubation is stressful.

There’s no way around that.

But it doesn’t automatically mean the hatch is ruined.

Eggs are tougher than most people expect.

Restore stable temperatures, give embryos time to recover, and try not to panic if hatch day shifts a little.

Because sometimes the difference between a failed hatch and a successful one…

Is simply giving the eggs a little more time.
