“The Cackle of Hens” W. A. K. Science Vol. 22, No. 554 (Sep. 15, 1893), p. 152
It is claimed that the cackling of hens “is very liable to attract the attention of any ovivorous bird or beast to the probable presence of an egg” It is quite probable that ovivorous birds or beasts may understand that the hen’s cackle is the announcement of the presence of an egg, but the hen is wise even in her apparent imprudence.
