In The Incubator

During the incubation period you will have to check on the eggs, and any slugs or unfertile eggs can be discarded. An unfertile egg can be discolored
or yellowing of the shell, growing of a fungus on it or just an unpleasant smell or sunken egg shell.
Moister must be monited, some times you might have to add a light misting of water to increase humidity in the container if the medium is drying out. Condensation should be seen on the lid at all times.
Also fanning of the eggs with the lid of the container to replace old air.
Eggs will start to sink as they are about to hatch.
Once your reptiles are starting to hatch you can remove and place in to another container, I like to reduce the temperature by a few degrees now and after a few days I remove them from the incubator and place in a tub or click clack container depending on species.
