Month: May 2024

Hi Div. 8 and families,

I have some exciting news.  Yesterday was Day 9 for the eggs that I have at home in the incubator, and Day 8 for the eggs we have in the classroom.  I have a video to share today of the Candling I did last night as I was checking on our eggs to see if they were growing.  Candling is the process of shining light through the air cell of an egg checking for the development inside an incubated egg.  

In the video you will see Egg #9.

Notice the following while watching the video: 

-The blood vessels -red lines going towards the center that resembles a red spiderweb.  These red blood vessels and veins are connected to the yolk and Albumin(egg white), and are responsible for absorbing the nutrients for the embryo to grow and develop.

-The embryo outline (looks like a bean shape)

-The black dot on the embryo, which is the eye. The eye is almost fully developed at this point.

-The Air Cell located at the top end (wide end of the egg).  This is the circular space you see almost as a light on the top of the egg.

Enjoy the video and we will talk more about it tomorrow!

Follow along with the development of our chicks.  This calendar is in the perspective of the CHICK!

Hello Division 8 Students, Parents and Families,

I picked up our chicken eggs on Thursday and they are now in the incubators.  12 eggs were put in on Thursday May 16th (rectangular brown EZ.SIMPLY incubator)

and another 12 eggs on Friday May 17th (Clear Round TRIOCOTTAGE incubator)

 

The eggs have been placed inside the incubator. This process is called “setting the eggs.”

Eggs must be physically turned to prevent the developing chick from sticking to the shell. More scientifically, the embryo should be resting on top of the yolk. The yolk tends to float upward, on top of the albumen (egg white) towards the shell if the egg is not turned. As a result, the developing embryo can be squeezed between the yolk and the shell, causing potentially fatal damage. By turning the eggs, the yolk turns within the albumin, once again moving the yolk away from the shell and making it safe for the embryo on top until it is time to turn again.

Eggs need to be turned a minimum of 3 times per day. Fortunately our incubators are automatic and it turns the eggs every two hours.

I will be bringing the Triocottage incubator to school on Tuesday May 21st and the eggs will remain in the incubator in the classroom until they hatch. The EZ.Simply Incubator will remain with me in my home, as it is a bit more finicky and I need to keep an I on the humidity level.  Incubation will be 21 days for each incubator, so that will mean that Hatch Day will be June 5th and June 6th.  We are super excited and hope you are as well.  Please stay tuned and I will post details about the stages of the embryos as they are developing. I look forward to keeping you informed and have you follow us on this incredible journey.

Warmly,

Denise Silva
