If hen leaves eggs after 1 day will they survive?

It depends on the species and incubation conditions. Generally speaking, hen eggs cannot survive for long without proper incubation. Chicken eggs require a temperature of around 37.5 degrees Celsius (100 degrees Fahrenheit) and a relative humidity of around 55-60%. If the temperature is too low, the embryos will not develop properly or will die. If the humidity is too low, the eggs will lose too much moisture and the embryos will not be able to develop.

Most hens will sit on their eggs for about 21 days. During this time, they will turn the eggs regularly to ensure even heat distribution and prevent the embryos from sticking to the shell. If a hen leaves her eggs after only one day, the chances of the eggs surviving are very slim. However, if the eggs are placed in an incubator and properly cared for, they may still be able to hatch.

Here are some tips for incubating chicken eggs:

* Choose fresh eggs that have been laid within the last 7-10 days.

* Place the eggs in an incubator that is set to a temperature of 37.5 degrees Celsius (100 degrees Fahrenheit).

* Maintain a relative humidity of around 55-60%.

* Turn the eggs at least three times a day.

* The eggs should hatch in about 21 days.
