This is our big automatic electric incubator - an Italian Corti model.
The turning motor is attached in this block on the side with an additional power supply. The turning motor is an addition, as it is possible to buy it without the turning mechanism - cheaper but more work. It means that if you use the mechanism, two sockets are needed.
This is it, empty. There is a water reservoir at each end, and that light blue toggle is the internal thing on which the rack sits which makes the rack move backwards and forwards to turn the eggs. It is very easily cleaned with some Flash.
Here is the plastic tray on which the eggs actually sit.
These dividers ensure that the eggs stay in one place and just rotate on the longest axis.
This is it, loaded up last night with the Cornish eggs at the front of the picture and my eggs behind.
