The 2024 Best Days to Set Eggs

Here are the best days to set eggs. Farmers swear that this age-old practice produces healthier chickens that mature faster. Learn more about calculating the best days to set chicken hatching eggs.

What is Setting Eggs?

Setting the eggs involves placing chicken eggs inside an incubator or under a hen. An incubator is an enclosed structure set to 100.5 degrees Fahrenheit with 50 to 55% humidity. It keeps eggs warm during the 21-day incubation period. When using an incubator, you set a minimum of six eggs at one time in the egg tray.

Why Are There Best Days to Set Eggs?

According to tradition, farmers swear that there are more “fruitful” times of the month to set eggs. Chickens hatched just before a full moon (during the waxing moon phase) would be stronger and have a better chance of survival. Conversely, chicks that hatched during a waning moon would be weaker.

Rather than picking any random date to set your eggs, try setting the dates by the Moon!

How to Calculate Dates to Set Eggs

We’ve found the best dates to lay eggs for this calendar year above. But if you want to know how it’s done, here’s the process: 

  • Chicks take about 21 days to hatch. 
  • Those born under a waxing Moon are healthier and mature faster. Further, those born in the fruitful signs of Cancer, Scorpio, and Pisces are healthier.
  • To ensure that chicks are born during these times, “set eggs” (place eggs in an incubator or under a hen) 21 days before the desired hatching time.


  1. The Moon is new on March 21 and full on April 6 (EDT). (See Moon phases for your area.)
  2. Between these dates, the Moon is in the sign of Cancer on March 28 through 30. (Reference The Moon’s Astrological Place calendar in The Old Farmer’s Almanac.
  3. To have chicks born on March 28, count back 21 days.
  4. Set eggs on March 7!
