The Octagon 40 DX Incubator supports Omnitherm heating, automatic egg turning & electronic temperature control with an independent built-in digital thermometer. It also holds twice the capacity of the Octagon 20. Even air-flow throughout the incubator is provided by two computer grade fans, whilst the level of fresh air drawn into the enclosure is controlled by a slider. The Octagon 40 DX is capable of hatching quail, hen or goose eggs, and is equally good with parrots and birds of prey. It is simple to use and clean and also comes supplied with a fully automatic egg-turning cradle.
