What temperature to incubate chicken eggs?
Perhaps the most important parameter is temperature – chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal) and 50 to 65 percent relative humidity (60 percent is often considered the ideal).uring the final three days of incubation, the eggs should ideally be located in a slightly cooler (98.5 degrees) and more humid (65 percent relative humidity or greater) environment to facilitate successful hatching. In a forced air incubator (with a fan) the temperature should be 99-99.5*F. In a still air incubator the temperature should be slightly higher, 101-102*F measured at the top of the eggs. I use a thermometer and a hygrometer (which measures humidity) in my incubator.ertility and Candling. Natural fertility is rarely 100% - it may vary from 55% to 95% with season, condition and type of birds. You might be safe to expect that 50% to 75% of the fertile eggs will hatch, though 90%-100% hatches can and does happen. 6. Record the day and how many eggs you've incubated on a calendar. You should be able to estimate your hatch date based on average incubation times for the bird species you want to hatch. For example, chicken eggs typically take 21 days to hatch, whereas many duck varieties and peafowl may take 28 days.. Record the day and how many eggs you've incubated on a calendar. You should be able to estimate your hatch date based on average incubation times for the bird species you want to hatch. For example, chicken eggs typically take 21 days to hatch, whereas many duck varieties and peafowl may take 28 days. Temperature: The eggs need to be kept at 99.5 degrees at all times; just one degree higher or lower for a few hours can terminate the embryo. Humidity: 40 to 50 percent humidity must be maintained for the first 18 days; 65 to 75 percent humidity is needed for the final days before hatching.t takes 21 days on average for an egg to hatch once incubation begins. Before placing the eggs inside, turn on the heat source and measure the temperature and humidity over a 24-hour period, making adjustments as necessary to create the optimal environment. Chicken eggs are incubated at 99 to 99.5 degrees. Chicken eggs incubate for 21 days. Your countdown for days starts when you put your eggs in your incubator. It does not start when the hen lays her eggs.Duck eggs are incubated at 99 to 99.5 degrees.hicken eggs incubate for 21 days. Your countdown for days starts when you put your eggs in your incubator. It does not start when the hen lays her eggs. Duck eggs are incubated at 99 to 99.5 degrees. 1 Temperature: Chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal). 2  Avoid temperatures outside the 97–103 °F (36–39 °C). 3  range. 4  If the temperature remains beyond either extreme for several days, hatchability may be severely reduced. Humidity: The moisture level in the incubator should be about 50 to 65 percent relative humidity (60 percent is often considered the ideal). 2  Moisture is provided by a pan of water under the egg tray. 3  You can use a wet bulb thermometer or a hygrometer to measure humidity. It takes 21 days on average for an egg to hatch once incubation begins. Before placing the eggs inside, turn on the heat source and measure the temperature and humidity over a 24-hour period, making adjustments as necessary to create the optimal environment.t takes 21 days on average for an egg to hatch once incubation begins.

Best Answer: Temperature should be 100'F for forced-air incubators and 102'F for still-air incubators. Check the temperature by placing the hatching thermometer at the same height as the top of the eggs would be.The heat source should be adjusted if needed. Humidity should be 58-60% from day one to day 18 and should be increased to 65% from day 18 to day 21. This is important to prevent moisture loss in eggs.est Answer: Temperature should be 100'F for forced-air incubators and 102'F for still-air incubators. Check the temperature by placing the hatching thermometer at the same height as the top of the eggs would be.
Between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal).
