Chullin 22 - Shavuot - May 22, 6 Sivan

Study Guide The Gemara introduces a braita to show the source for the debate between the rabbis and Rabbi Elazar b'Rabbi Shimon in a bird burnt offering. The braita presents three distinct opinions on the biblical term "k'mishpat" regarding a bird burnt offering. The Sages debate whether this term compares it to an animal sin offering or a bird sin offering, detailing the exact procedural laws they share. This very debate serves as the foundation for the conflicting views of the rabbis and Rabbi Elazar b'Rabbi Shimon regarding whether the two simanim must be severed completely. The Mishna states the age rules for birds for sacrifices: mature turtledoves (torim) are valid while young ones are not, whereas young pigeons (bnei yonah) are valid while mature ones are not. The Gemara defines the exact boundaries of these stages, analyzing the transitional phase known as techilat hatzahov (when the plumage around the neck begins to turn a golden/yellow color), which is disqualified in both species.
