Humidity of incubator for chicken eggs10/5/2023 ![]() One time-saving feature is a device to rotate the eggs automatically. These have a sensor that goes inside the incubator with an LED screen on the outside that shows the temperature and humidity readings without having to open the incubator and ruin your carefully calibrated environment. If you are not working with an incubator that has these instruments built in, opt for a combo thermometer/hygrometer with an external display. Cheap models are usually not accurate enough. Low-end commercial incubators don’t amount to much more than this, but the more you pay, the more automated the temperature and humidity controls will be.Ī high-quality thermometer and hygrometer (a device to measure humidity) are the most important tools of incubation. An adjustable heating pad or a light bulb on a dimmer switch will suffice for the heat source, and a pan of water with a sponge in it will make the air humid. Homemade versions usually involve some sort of insulated box – a cheap Styrofoam cooler will do. Incubators need to have holes or vents that allow fresh air to circulate so the fetuses can breathe. Ventilation: Egg shells are porous, allowing oxygen to enter and carbon dioxide to exit. Humidity: Forty to 50 per cent humidity must be maintained for the first 18 days 65 to 75 per cent humidity is needed for the final days before hatching. 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. No matter how fancy or jerry-rigged, all incubators must accomplish a few basic things. You can also go the do-it-yourself (DIY) route, which saves money but is almost as much work as sitting on the eggs yourself. With top-of-the-line incubators, you put in an egg, close the door and out pops the chick three weeks later. Plus, why would you want to miss out on an opportunity to experience one of life’s miracles?ĭepending on how many eggs they accommodate and how automated they are, incubators run from around $50 for the homesteader favourite,‘Hova-Bator,’ into the thousands of dollars for commercial scale incubators. You can also buy day-old chicks and skip the incubation process, but it costs more. There’s no shortage of things that can go wrong.įor this reason, most farmers and backyard chicken enthusiasts don’t trust incubation to their hens, they take it upon themselves to do the brood work instead. ![]() Whether it is genetic or culture, who knows, but they get distracted, other hens oust them from their nest, the rooster comes by. Modern chickens, it turns out, are not always very effective mothers.

Incubation RH, hatching time, and sex did not affect feed intake, feed conversion, or rectal temperature. Chicks exposed to the experimental temperature regimens had lower rectal temperatures than controls at the end of the 1st and 2nd wk. Chicks hatching late were heavier at Day 2 than early-hatching ones, but body weight gain was similar. These chicks also had higher body weight gain in the 1st and 2nd wk following exposure to 39 C than chicks hatched from eggs incubated at 55% RH. At Day 2 of age, chicks hatched from eggs incubated at 45% RH had higher body weights than chicks hatched from eggs incubated at 55% RH. Chicks exposed to the experimental temperature regimens for 2 days had lower body weights at the end of exposure and grew less than controls during the 1st wk afterwards. After exposure, a 4-wk experimental growing period started at Day 2 of age. ![]() The other chicks were exposed to 35, 37, or 39 C for 48 h. After hatch, 60 chicks served as controls. Within each RH group, two groups were separated based on hatching time (early and late hatch groups). The chicks hatched from eggs incubated at a relative humidity (RH) of 55 or 45%. Three experiments were performed with 300 neonatal Hisex Brown layer chicks in each.
