Chulin 12:1-2

Chulin 12:1

The obligation to send away a mother bird before taking the chicks or eggs applies both in Israel and elsewhere, both when the Temple is standing and when it isn’t, to secular animals but not to sacrifices. Covering up a slaughtered animal’s blood is more stringent than sending away the mother bird in that it applies to both kosher wild animals and birds, whether they are farmed or caught, but sending away the mother only applies to birds, specifically those that one doesn’t raise. Examples of birds that one doesn’t raise include geese and other fowl that, while domesticated, make themselves nests in an unguarded place. If they made their nests in the house – and, similarly, Herodian doves (which were raised inside) – one need not shoo away the mother.

Chulin 12:2

One is not obligated to send away the mother of a non-kosher species of bird. If a non-kosher bird sat on the eggs of a kosher bird, or a kosher bird sat on the eggs of a non-kosher bird, one need not shoo it away. Rabbi Eliezer says that one must send away a male partridge sitting on its eggs but the Sages say that this is not necessary.
