לרבות אפרוחים שלא נפתחו עיניהם מדרבנן וקרא אסמכתא בעלמא serves to include chicks of pigeons whose eyes have not yet opened in the prohibition against consuming swarming things. The Gemara responds: This prohibition is by rabbinic law, and the verse cited is a mere support for it. One who eats the embryo of a kosher bird is not liable to receive lashes.
תנו רבנן גיעולי ביצים מותרות ביצים מוזרות נפש יפה תאכלם נמצא עליה קורט דם זורק את הדם ואוכל את השאר § The Sages taught in a baraita: Kosher eggs that have been boiled with non-kosher eggs are permitted. Unfertilized eggs are permitted, and one of strong constitution may eat them, even if the hen has sat on them for a long period of time. If a drop [koret] of blood is found on it, one discards the blood, which is the first stage of an embryo’s development, and eats the rest.
אמר רבי ירמיה והוא שנמצא על קשר שלה תני דוסתאי אבוה דר' אפטוריקי לא שנו אלא שנמצא על חלבון שלה אבל נמצא על חלמון שלה אפי' ביצה אסורה מאי טעמא דשדא תכלא בכולה א"ל רב גביהה מבי כתיל לרב אשי איפכא תני תנא קמיה דאביי ואביי הוא דתרצה ניהליה הכי Rabbi Yirmeya said: And this applies when the blood is found on its knot, i.e., the place in the albumen where the embryo begins to develop, since this proves that tissue has not developed elsewhere in the egg. And so taught Dostai, father of Rabbi Aptoriki: The Sages taught that one may eat the rest of the egg only when the blood is found on its albumen, i.e., the knot; but if it is found on its yolk, even the rest of the egg is forbidden. What is the reason for this? It is that the decay has spread through all of it. Rav Geviha from Bei Ketil said to Rav Ashi: A tanna taught the opposite before Abaye, that one may eat the rest of the egg only when the blood is found on its yolk, and it is Abaye that corrected it in this manner.
אמר חזקיה מנין לביצת טמאה שהיא אסורה מן התורה שנאמר (ויקרא יא, טז) ואת בת היענה וכי בת יש לה ליענה אלא איזו זו ביצה טמאה ודלמא היינו שמייהו לא סלקא דעתך דכתיב (איכה ד, ג) בת עמי לאכזר כיענים במדבר § Ḥizkiyya says: From where is it derived that the egg of a non-kosher bird is prohibited by Torah law? As it is stated: “And the daughter [bat] of the ya’ana” (Leviticus 11:16). But does the ya’ana have a daughter whose forbidden status would be different from that of its mother? Both daughter and mother should be included in the same prohibition. Rather, which is this? This is a non-kosher egg. The Gemara challenges: But perhaps this is their name, i.e., the bird is called bat ya’ana. The Gemara responds: This should not enter your mind, as it is written: “The daughter of my people has become cruel, like the ye’enim in the wilderness” (Lamentations 4:3).
ולא והא כתיב (מיכה א, ח) אעשה מספד כתנים ואבל כבנות יענה כיענה זו שמתאבלת על בניה והא כתיב (ישעיהו יג, כא) ושכנו שם בנות יענה כיענה זו ששוכנת עם בניה The Gemara persists: And is bat ya’ana not its name? But isn’t it written: “I will make a wailing like the jackals, and a mourning like the daughters [benot] of the ya’ana” (Micah 1:8)? The Gemara responds: The verse means: I will make mourning like this ya’ana that mourns for its children. The Gemara asks: But isn’t it written: “And benot ya’ana shall dwell there” (Isaiah 13:21)? The Gemara responds: Here too, the verse means: And they shall dwell there like this ya’ana that dwells with its children.
והכתיב (ישעיהו מג, כ) תכבדני חית השדה תנים ובנות יענה ואי סלקא דעתך ביצה ביצה בת מימר שירה היא אלא כתיב היענה וכתיב בת היענה The Gemara asks: But isn’t it written: “The animals of the field shall honor Me, the jackals and the benot ya’ana” (Isaiah 43:20)? And if it enters your mind that the term bat ya’ana is referring to an egg, can an egg sing a song of praise to God? Rather, one must say: The ya’ana is written, and the bat ya’ana is also written, and both are acceptable names for this bird.
ושאני הכא דפסק ספרא לשתי תיבות ומדפסיק להו ספרא And still, the name here is different from those of other animals, in that the scribe splits it into two words: Bat ya’ana, even though it is one species. And from the fact that the scribe splits it
