Humidity of incubator for chicken eggs12/14/2023 If you choose a small incubator without an egg turner, just remember that it is up to you to turn the eggs at least twice a day.Įxperts recommend that you set the temperature of your still-air incubator to 101 to 102 degrees to best avoid the formation of cold spots on the inside. Incubator capacity and price vary widely, so it’s wise to consider how many eggs you are likely to hatch in a year before you take the financial plunge. Both types of incubators may be equipped with automatic or manual egg turners, and both offer some means for managing relative humidity. Forced-air incubators use a fan to circulate internal air. Still-air incubators lack mechanical air circulation. There are two principal categories of incubators suitable for the home flock: still-air and forced-air. When most folks think of incubating eggs, their minds turn to any manner of electromechanical devices that provide the right temperature and humidity. Many folks try to prevent their laying hens from going broody because they don’t lay eggs while hatching and raising chicks – if you want to hatch a few chicks though, a broody hen can be a godsend. If you already have a laying flock and one of your hens becomes broody, she can incubate her own eggs, or you can place fertile eggs obtained elsewhere in her nest, and she will do her best to hatch them. A broody hen will take care of ventilating and warming the eggs and will handle all of the turning and chick-rearing duties as well. What’s a broody hen, you wonder? This hen has undergone progesterone-induced changes that make her want to sit on eggs to hatch them and brood the resulting chicks. The easiest way to incubate and hatch fertile chicken eggs is to have a broody hen do all the work for you. During the hatching phase, it’s best to lay the eggs on their sides. In general, eggs should be incubated with their pointed ends down (air cell up) – but it is also important to turn or tip the eggs back and forth at least twice a day – the more often they are turned, the better. Changing an egg’s attitude helps exercise the embryo and prevent it from sticking to the shell. Just as temperature and humidity are important to maximizing the hatch, eggs need to be moved around on a regular basis for best results. Lowering the temperature helps account for the extra heat that the larger embryos produce as a result of their metabolism, and the increased humidity helps keep the chicks from getting stuck to the membrane that’s located just inside the egg shell as they break out of the shell. During 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. Consider that number to be a target – not an absolute. To facilitate proper aeration and gas exchange between the embryo inside the egg and the outside world, the eggs must not be held in a tightly sealed container.Ĭhicken eggs typically hatch after 21 days of incubation. 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). Incubation TemperatureĬhicken eggs need a fairly specific environment to develop properly and hatch successfully. Hatching fertile eggs need not be difficult, but your success rate can be increased by following a few guiding principles. Likewise for folks who keep a rooster in their flock, incubating eggs is a great way to increase the flock size, or to provide replacements for birds that have been culled. For folks who are uncertain about receiving live animals through the mail, or simply cannot handle the minimum number of day-old chicks that most hatcheries require, incubating fertile eggs is an attractive alternative. But that’s not the only way to create your first flock or maintain your existing one. Which came first, the chicken or the egg? For most backyard poultry enthusiasts, the chicken came first – well, more correctly, the day-old chicks first arrived in the mail. A broody hen takes the work out of incubating eggs.
