The science department is hatching eggs again this year.
The eggs are getting weighed at regular intervals and their mass is recorded by students. The eggs should lose 13% of their mass by the time they are ready to hatch. So far, they are losing the correct amount of mass.
We have also been able to 'candle' the eggs and have seen the developing chicks. So far everything is looking good!
Here are some photographs of our new additions to the school role.
The picture below is a live webcam feed that did show the eggs in the incubator. The image will be refreshed every 20 seconds and should now introduce to our new chickens. Below that are a few pictures showing the preparation needed.
Information about hatching chicks
A mother Hen will sit on the eggs for over three weeks, brooding them at 37.5 degrees Celsius, only getting up for food and water and spending as little time away from the nest as possible. She will occasionally turn the eggs and move them around so that they're warmed on all sides. A few days before the chicks are ready to hatch, they will break through the internal membranes with their egg teeth and begin chirping. At this point the Hen will stop turning them, as she'll know they're on their way. It can take up to 24 hours for the chicks to fight their way out of their egg shells, and they'll be exhausted after they flop out. They'll be busy for the first few hours of their lives, trying to find their feet while their feathers dry.
Did you know? Not all chicken are yellow and some can be heard chirping in their shells up to 24 hours before they hatch?
