Eggs that needed a higher humidity were placed into the 65%RH incubator for a few days, then re-weighed, they were brought back, closer to the ideal weight loss line on my graph. Raise and lower the temperature of the heat source in tiny increments until the thermometer reads 99.5. It's purpose is to keep temperature and humidity at defined values, so that the eggs … Humidity control. There is no "ideal" humidity for everyone, key is to finding the ideal humidity for your particular eggs and the best way to do this is by monitoring the air cells or weighing the eggs. Then I will adjust to even out temps. Precise and consistent control of temperature is essential for good hatching results. The eggs can hatch but the chicks would have deformities and can eventually die. I find (unless you are in a high elevation or are using a cabinet incubator) that low humidity incubation (especially in styro bators) work best for chicken eggs. Before spending time and effort checking incubation humidity levels it essential to ensure that temperature and egg turning are correct - refer to the unit’s operating instructions. Humidity control. The humidity is maintained by opening and closing an air vent on the incubator using a servo. Also, I should mention, once you have eggs in the incubator the temps and humidity will be wonky until the eggs come to temp and they’ve had a few hours. A good quality egg incubator has a built-in temperature alarm which warns of high or low temperatures. Also check that the eggs are fertile and the parent stock healthy, properly fed and free from in-breeding. By all indications, the Brinsea Products USAG47C Ovation incubator may be the best egg incubator for the money. If the incubator is too hot you can open the ventilation shafts more and if it is too cold you can close the ventilation shafts more. Humidity should be around 45 to 50 percent throughout incubation, except during the last three days when you will want to raise it to 65 percent. You may need higher or lower humidity levels depending on the type of eggs you wish to hatch. The over-temperature phenomenon when incubating chicken eggs. The water warms up and evaporates, the humidity rises, the vent is opened and the humid air can escape letting dryer air in. Once the incubator is functioning properly, it’s just a matter of maintaining the environment until the chicks hatch. A good quality egg incubator has a built-in temperature alarm which warns of high or low temperatures. Monitor the incubator’s temperature on a regular basis; Train the person-in-charge of the incubation well. Please refer to the recommended temperature and humidity per instructions and consider the outer temperature. A wide variety of humidity for egg incubator options are available to you, such as household, industrial, and indoor. Is an arduino controlled incubator for chicken's eggs. Incorrect temperature or humidity levels when incubating chicken eggs causes harm to the chicks. Egg shells are porous and they allow water to pass through. The water warms up and evaporates, the humidity rises, the vent is opened and the humid air can escape letting dryer air in. 4.During different incubating processes, the temperature and humidity are varied. The effect of humidity upon the incubating egg Humidity in Incubator is the most important thing to maintain correctly together with the temperature. A well-designed incubator should maintain temperature within 1/4 degree F and humidity within 1 degree F wet bulb temperature. A well-designed incubator should maintain temperature within 1/4 degree F and humidity within 1 degree F wet bulb temperature. Embryos fail to develop or even die when the humidity in the incubator is not right. The servo angle is determined by the humidity PID loop. About 11% of these are temperature instruments, 1% are sensors, and 1% are testing equipment. The correct temperature for incubating pheasant eggs is 99.5 degrees, but typically within 1 degree range should still yield you a successful hatch. The servo angle is determined by the humidity PID loop.

The amount of water that an egg loses during incubation is important and is determined by the humidity levels in the incubator.
