Fact #3: Chickens have their own “language.”
It’s thought that chickens have about 30 distinct vocalizations that they use to communicate with each other. For instance, the warning cry for a predator that is coming on the ground is different from the cry for a predator coming from above.
Fact #4: Chickens sometimes model their behavior on other chickens.
The special way a broody hen clucks can encourage other hens to become broody, too.

Fact #5: Chickens begin communicating before they are hatched.
Chicken families begin communicating with each other before the babies have even hatched. The mother hen talks to her eggs (often a purring sound), and the chicks begin peeping back to her from inside their unhatched eggs.
Fact #6: Chickens are more docile at night.
Chickens go into a passive, trancelike state when they sleep at night. Consequently, if you need to catch and handle a chicken that is not very tame, do it at night after the chicken has settled down to roost.
Fact #7: Chickens learn who you are.
Chickens can recognize up to 100 faces!

Fact #8: Chickens lay different colors of eggs depending on breed.
Blue eggshell color comes from biliverdin; brown eggshell color comes from protoporphyrins. Pink eggs are the result of small quantities of a rosy brown pigment, while green eggs have both blue and brown pigments.
Fact #9: Chicken eggs are nutritionally about the same regardless of color.
Brown eggshell colors are deposited on the outside of the shell, while blue goes throughout the shell, even on the inside.
Fact #10: Chickens signal when they are ready to lay.
Before a hen begins to lay, her comb will get larger and redder, and she may begin to squat submissively when you reach down to pet her.
