Deuteronomy 22:6-7

6“If you happen to come upon a bird’s nest along the way, in any tree or on the ground, with young ones or eggs in it, and the mother sitting on the young or on the eggs, 1you shall not take the mother with the young; 7you shall certainly let the mother go, but the young you may take for yourself, 2in order that it may go well for you and that you may prolong your days.
