How to Incubate Guinea Fowl Eggs

How to Incubate Guinea Fowl Eggs

So you want to hatch some Guinea Fowl eggs? Before you even start the incubation process, there are things you need to do.

Guinea Eggs

Guinea Fowl eggs can be stored for up to 7 days, but, when storing guinea fowl eggs to incubate, make sure that they are kept at a constant temperature of 64.5-68 degrees Fahrenheit.We store our eggs on an automatic egg turner in our basement until we are ready to put them in the incubator.

If you don’t have an automatic egg turner, you will need to make sure the stored guinea fowl eggs are turned at least three  times daily before they are incubated.

Preparing The Incubator

Don’t even think about incubating the guinea fowl eggs until you make sure that the incubator is thoroughly cleaned and  disinfected. Clean incubator thoroughly using water and a mild disinfectant soap. Allow to dry completely while disassembled before proceeding.

Begin preparation of the incubator one or two days prior to setting the eggs, to ensure correct temperature and humidity  levels are maintained.

Always put the incubator in a room with a constant temperature. Drafty rooms will cause the heat in the incubator to fluctuate. The ideal place is a low-traffic room, free of direct sunlight and drafts. Steer clear of heat sources and air vents.

It is good to keep the incubator on a table or other stable, elevated surface. There will be water in it, so it has to be level. Always fill the water trough as directed by the incubator’s instructions and check that the incubator is in working order before adding the guinea fowl eggs.

Place the mesh floor in the incubator, followed by the turner, if you are using one.

Place the thermometer/hygrometer in a location where the reader will be level with the yoke of the eggs. Make sure it can be easily read from the outside. place it close to the center of the incubator, but away from the heating element. A wet/dry bulb thermometer should have its wick in the water, but be kept out of the way of the turner.

Place the lid on the incubator, making sure all seals and windows are airtight. Plug in the power cord.

Calibrate the incubator until the internal temperature remains at 99.5 degrees Fahrenheit (101.5 if using a still-air model) and relative humidity is at 58-65% .

Allow the incubator to warm up and settle at the correct temperature and humidity before adding the guinea fowl eggs.

Guinea Fowl Hatching Tips

Place eggs in incubator with the small end facing down.

The incubation period for a guinea fowl egg to hatch is 28 days. The length of the incubation period can vary between 26 and 30 days, if the temperature or humidity is off a bit in the incubator.

The correct temperature in an incubator with a fan is 99.5 degrees Fahrenheit, decreasing to 98.5 degrees Fahrenheit during the final three days of incubation. If you have a still air incubator, set it at 101.5 degrees and decrease to 100.5 the last three days.  Keep careful track of temperature and humidity throughout the incubation process, as a variance of a single degree can be problematic for the eggs.

The correct humidity for hatching Guinea Fowl eggs is 65% until day 25 and then rising it to 80% until day 28. You can raise humidity by adding water in the water troughs at the bottom of the incubator. You need to be sure that the water troughs are filled with water at all times.

Keep ventilation holes open. Good ventilation is essential for a successful hatching. Eggs are living and breathing things.

The guinea fowl eggs will need to be turned daily and this can either be done by hand, or by using an automatic egg turner.  Automatic egg turners will turn the eggs every 4 hours. Make sure eggs are turned 4-6 times each day. If not using a turner, make a small mark on each side of the egg to avoid confusion during hand turning. X on one side O on the other.

On day 25, the eggs no longer need to be turned. The automatic egg timer can be removed, if you are using one. Add clean  water to all the troughs to raise the humidity. Put a sponge soaked in warm water directly below the vent holes. That way you can add water to raise the humidity without opening the incubator. We use a turkey baster inserted in the vent hole to add warm water to the sponge.

Increase relative humidity to approximately 90 degrees Fahrenheit for the last three days of incubation. Keep air vents open.

It’s also a good idea to keep a daily record of what’s going on with every incubator hatch.

Hatching Guinea Fowl

When the guinea fowl eggs start to pip, allow 24-48 hours for the hatch to finish. Most guinea fowl eggs will hatch within a day or so, but sometimes weaker guinea fowl chicks (keets) may hatch a day or two later.

Don’t remove the keets from the incubator until they are dry. Then move the keets to a brooder with water and chick crumbs as soon as possible.

Discard any unhatched guinea fowl eggs after four days.

Always remember to thoroughly clean and disinfect the incubator after each set of eggs have hatched.


Here is a nice COLOR CHART to see what colors of Guinea and Keets you might have.

    Thanks for the straightforwad instructions.
    Others like to confuse me with wet and dry bulbs and metric temperatures. None of which are available to me or understood by me.

  2. Country Girl NY says:

    Thanks! I’ve been looking for instructions like this all day!

  3. Tim says:

    Why do you decrease temp on 25th day? what happens if you don’t? how does the guinea hen decrease the temp ?

  4. Lisa says:

    We are trying to hatch guineas in our incubator and not having any luck. After the 28 days still nothing, we wait 4 to 5 days later and still nothing. We opened a few up and to our surprise it looks like the keets are still developing. They start breathing but don’t make, they still have the sac attached to them. It’s like they needed more time. Please let us know what we are doing wrong. We are using a still air incubator and it said to keep the temp at 99.5 but now on things we read it says to have the temp at 101.5. Which is correct?

  5. chansenAdmin says:

    99.5 is correct for a forced air incy. 101.5 is correct for a still air.

    please advise me i have bought an incubator and i need to hatch guinea eggs

  7. chansenAdmin says:

    Just follow the directions in my post. They are pretty easy to hatch. Watch your temps and humidity close.

  8. Sophie says:

    Hi my grandchildren are going to incubate a few of my guinea eggs. Must they wash them first. Some say no some say yes. My eggs are very clean to begin with.

  9. chansenAdmin says:

    I would never wash eggs before incubating them! It takes the natural “bloom” off the eggs that protects them from bacteria. I’ve had the dirtiest and nastiest eggs hatch just fine, sometimes better than clean ones. lol I just keep nest box materials clean and the eggs stay pretty clean.

  10. Sophie says:

    We had a few guines’s eggs peep inside the egg in our incubator but never hatched. What could of caused that to happen

  11. Carol Hansen says:

    You may not have had the humidity right and they couldn’t turn to zip out of the egg.

  12. Deborah Shevenko says:

    I found 3 Guinea eggs yesterday in a hole one of my Guineas dug. Today it rained and the eggs were totally submerged in water. My husband ran out and took the eggs out of the water and moved them to a dry location. Will they still hatch? And will the mother still care for her eggs?

  13. Carol Hansen says:

    I doubt she will return to the eggs if you moved the nest. Being in water could have ruined the eggs as well. Good luck.
