What is the meaning of "Hikshi'ach Baneha l'Lo Lah"?
Rashi: It hardened its children from its heart, as if they are not its children.
Ibn Ezra: It is cruel to its children, as if they are not its children. We do not find this elsewhere in Tanach, except for "Takshi'ach Libenu mi'Yir'asecha."
Malbim: Also after the chicks hatch, it is callous to them, as if they are not its. Scientists say that Bas ha'Ya'anah puts a rotten egg over its buried eggs. Worms come from it, for its children to eat; it does not toil more than this to raise its children.
Why does it say "la'Rik Yegi'ah Beli Fachad"?
Rashi: It does not worry lest it lose its children. Malbim - it is not worried lest its toil to give birth be for naught. Therefore, it does not guard its eggs and children like other birds.
