On Friday, we took out the automatic egg turner. The eggs no longer need to be turned after day 18. We will now prepare the incubator for the hatching of the baby chicks.

1.Open the incubator

2.Take the eggs out of the automatic egg turner and place them carefully in the egg cartons that they arrived in.

3.Unplug and take out the automatic egg turner.

4.Place a layer of cheese cloth (like a very thin paper towel) and place over the wire rack.

5.Add sponges to the bottom channels of the incubator to increase moisture. Fill with water.

6.Place the eggs back on to the cheese cloth. The eggs will now rest on their sides.

7.Close up the incubator.

8.Remove the red vent plug from the top.

The eggs are here! Stop by and visit them today!

We have eggs at the library! Today, I picked them up from the Midlothian Park District. We received 36 eggs. Our eggs went for a nice car ride to the library.

Here they are bundled up in a blanket to keep them warm and safe.

After I brought the eggs to the library, we let them warm up to room temperature.

Here are the library's 36 eggs!

Next, we added an X and and O to each side. This will help us know that the eggs are gently rocking back and forth. The eggs need to be turned 3 times a day so that the baby chick does not get stuck to one side of the egg. Our automatic turner gently rocks them back and forth. We also numbered the eggs 1 to 36.





Here are the eggs inside the incubator.

A chick cake to celebrate! So cute!!
