I’m a great believer in agricultural traditions and folk wisdom.
That’s because much of what I learned about homesteading was passed onto me by the two generations of garden farmers that came before me. Heeding their advice enabled much success and fewer homesteading failures.
One bit of advice that was given to me by those far more experienced than myself was regarding the best time for setting or incubating eggs.
The most favorable time for setting eggs under a broody hen or in an incubator is 21 days before a waxing moon is in the zodiac sign of Cancer.
In order to determine what day that would be you’ll need an almanac for the current year. All good almanacs have tables or charts that map the course of the moon though the zodiac.
If we use chicken eggs as an example here’s how to find the best day.
Chicken eggs need 21 days to hatch.
So a quick look in any current almanac will find days that the moon will be in the sign of Cancer, and will also be waxing.
Most years there will be a couple of days that this will occur during the light (waxing) of the moon.
All that is necessary is to pick a Cancer, and then count backwards 21 days. Whatever day that happens to be is the day to begin to incubate the clutch of eggs. That day counts as Day 1.
If for some reason a waxing Cancer day is inconvenient for setting eggs, a day that a waxing moon falls in the signs of Scorpio or Pisces would be a second best choice.
Chicks that are hatched during a waxing Cancer moon tend to hatch with fewer problems and grow faster.
