He is gone so now I am your teacher, back to bussiness.
Today we will be talking about two out of the four parts of incubation: temperature and humidity.
What kind of eggs are they?
Where is my teacher?
I thought I was the teacher here!
The other two parts of incubation are turning the eggs and humidity.
Well you are not teaching me anything like a teacher is supposed to.
Remember, if the humidity is too low at hatch time the chicks will have trouble hatching.
Lets talk about some of the temporary organs in the embryo.
Now a chicken is my teacher!
I feel like am going to lay another chicken egg.
I know, but it isn't. We could see the heart beating and blood vessals.
The temperature should be between 99 degrees and l0l degrees. If it is lower than 92 degrees or higher than 105 degrees the chick will die. In the incubator, the air should be fresh and unpolluted. Students should not use marker to label their eggs and do not use strong chemicals.
What, Angelina? I am tired of guessing!
Ok, so we candled today and the chicken embryo look like a question mark!
Hey! Guess what Bob!
When you turn the eggs make sure you wash hands before and after turning the eggs. Each day gently turn the eggs. Turn the eggs an odd number of times each day to ensure they do not sleep on the same side each night. Do not turn them three days before the expected hatch.
Also the scales, feathers, and claws are completly formed.
Today was day 15 and the albumen is almost gone!
I know! We saw the embryo turn to the blunt end of the egg!
Ok, so one of the temporary organs is the allantois. It has two uses: one is that it collects the waste of the embryo. Yes, a embryo poops too. The other use is for respiration which is the embryo's lungs, helping the embryo to breath. The amnion is protection for the embryo. It is located around the embryo.
5 days latter....
Hey mom! Today was day 20!
Yeah, but the yolk sac is in the chicks abdomen.
One more day untill the chicks hatch!
It also broke into the air cell and took its first breath and became a chick!
