This is an egg incubator which was used for hatching chicken eggs. Mechanical incubating was not invented until the year of 1749 by Reamur in Paris, France. Prior to this invention, one of the first recorded methods of incubating included using the heat of rotted manure to warm the eggs.
Although this incubator is mechanical, it was still before the availability of electricity to farms, instead, a coal oil lamp was used to heat water, circulating by convection through pipes around the perimeter of the incubator. This incubator is a cabinet style, made of redwood and could be suitable for indoor decor. Very few of these can be found today, making this item rare, especially because the incubator still has the original kerosene attachment. The cabinet style has drawer pull-outs for placing the eggs and for turning. Most incubators required hand turning of the eggs.
