Today is 7.

 7 is how many days we've had the eggs. The egg tooth is starting to grow. The egg tooth is the tooth that the chick uses to break out of the shell when it's ready. The temperature is near 100. The incubator is keeping the chicks warm because  we don't have a mother hen. The chicks are growing and they will get out of the egg all by themselves because if a person did it they would die.
