In our class, we are hatching chicks. There is something called an incubator that acts like a mother hen sitting on her chicks. It is supposed to be at one hundred degrees Fahrenheit in the incubator. We have a hatching calendar. It takes twenty-one days for the chicks to hatch. On day one, the chick’s nervous system develop. On day two, the chick’s heart starts beating and blood vessels start to appear in the in the yolk. There are too many steps to explain. On the twentieth day, the chick will break into the air sac and start breathing. On the twenty first day, the chick is ready to hatch. Here are some parts of a chicken: the comb (fleshy part on top of the chicken’s head) , the beak, the breast, the shank (a part on the chicken’s leg) , the wattle (the part under the chicken’s beak) , the tail feathers, the wings and the toes. Here are some parts of the egg of a hatching chick: membrane (thin but strong layer near the shell that protects the chick during development against infection) , air cell (it forms at the larger end of the egg and is where the chick will turn to as it develops) , the chalazae (this is part of the albumin – the albumin is the egg white and protects the yolk and gives protein to the embryo – the unborn chick at the early stage of development) The germinal disc (is on the egg yolk and helps the embryo in the early development). We put 24 eggs in the incubator.  We don’t think they will all survive.  I can’t wait to see the chicks.
