||If you come across a birds's nest on any tree or on the ground, and it contains baby birds or eggs, then, if the mother is sitting on the chicks or eggs, you must not take the mother along with her young.
Ki yikare kan-tsipor lefaneycha baderech bechol-ets o al-ha'arets efrochim o veytsim veha'em rovetset al-ha'efrochim o al-habeytsim lo-tikach ha'em al-habanim.
||You must first chase away the mother, and only then may you take the young. [If you do this] you will have it good, and will live long.
Shale'ach teshalach et-ha'em ve'et-habanim tikach-lach lema'an yitav lach veha'arachta yamim.
Only a kosher bird (Chullin 139b).
(Sefer HaMitzvoth, Negative 306; Chinukh 544; Chakham Tzvi 83; Septuagint; Bachya; Chizzkuni; cf. Chullin 141a). Or, 'from on' (Targum Yonathan; Sifri; Tur, Yoreh Deah 292. Cf. HaKethav VeHaKabbalah; Minchath Chinukh 544).
(see Chiddushey HaRan, Chullin 139a; Teshuvoth Rashba 18, 3:283). However, some maintain that it is a meritorious deed to send away the mother even if one does not wish to take the young (Teshuvoth Chavvoth Yair 67; cf. HaKethav VeHaKabbalah).
