I still could not get humidity above 36% and was adding a half a glass of water when I turned/tipped eggs twice a day.was really confused. When I correct humidity, I add warm water. To test humidity- the thermometer is also a hygrometer, so always know what it is. I don t actually turn them.have them in a plastic egg tray that has open bottoms and use a block under one side that gets moved to other side twice a day. If I need to add water I do it through one of the plugs or when I am "turning" eggs. I only open the bator twice a day when "turning" eggs. The bator is in my bedroom on a hutch, away from the window and doors (no heat running through vent- have an electric heater in there which keeps the temp stable) as that is the room with the most stable temperature and the door is always shut as I don't allow animals in my bedroom uninvited, plus that is the only room I keep heated at all times since my sleep schedule and hubbies are different and vary from day to day. They have been in the bator since Sunday. Purchased a digital thermometer/hygrometer which is sitting in the incubator next to the eggs.

Incubators have contributed to the much-improved infant survival rate, even of very low birth-weight infants. The incubators are made of plastic and Plexiglas. Today incubated infants are enclosed in chamber that is well ventilated (allows for the movement of air), with the temperature maintained at about 31 to 32 Celcius (88 to 90 Fahrenheit). A number of "incubators with living children" were demonstrated in Turin, Italy, at the 1898 Italian Exhibition. It was warmed by a kerosene flame and used at the Paris La Maternite (a birthing hospital). Etiene Stephane Tarnier, a French obstetrician (1828-1897), devised an incubator for the care of prematurely born infants. Often, the incubators were warmed by pans of hot water placed under them. The 1880s saw the introduction of incubators to keep premature (born too early) or extremely weak babies warm. Modern egg incubators are huge and may handle a million eggs at a time. The incubator was further developed by Abbe Jean-Antoine Nollet (1700-1770) and later by Abb é Copineau, who used alcohol lamps as a source of heat. The success of Reaumur's incubator -French king Louis XV (1710-1774) enjoyed helping the chicks hatch -helped boost commercial production of foodstuffs at the beginning of the industrial era. The temperature was controlled by a thermometer he also invented, which gave rise to the temperature scale named after him. Reaumur's device was warmed by a wood stove. Later on, Dutch inventor Cornelius Drebbel also invented an incubator to hatch eggs.įrenchman Rene-Antoine Ferchault de Reaumur (1683-1757) revived interest in egg incubation in Europe around 1750. He was forced to abandon his work during the Spanish Inquisition (a 1478 movement instituted by King Ferdinand and Queen Isabella of Spain during which many people were tortured and killed in the name of religion). In 1588 Jean Baptiste Porta, an Italian inventor, drew on the ancient Egyptian design to build an egg incubator. Chinese incubators were warmed by fire or by rotting manure. Egyptian incubators were large rooms heated by fires where attendants turned the eggs at regular intervals so they would warm evenly. This enabled hens to continue laying eggs without interruption. The ancient Egyptians and Chinese both devised incubators to hatch chicks from eggs without having the mother hen sit on them. An incubator is an enclosed chamber used for maintaining a living organism in a controlledĮnvironment.
