2 A nest that is considered “prepared” for him—for example, doves that usually grow up with humans in houses, and geese or chickens that made their nests in a house—he is exempt. But doves of a dovecote or an attic, and birds that made their nests in tapichim (clay vessels built into walls where birds nest), and in pits, and geese and chickens that made their nests in an orchard—he is obligated to send away the mother. This applies only if the mother has not been lifted from the eggs at all since she laid them. But if the mother was lifted from them, then if those places belong to him, his courtyard acquires them for him, making it “prepared,” and he is exempt.
