Chapter 2! A new mishnah... On slaughtering a "bird," where cutting one "siman" (windpipe or gullet) is sufficient for kosher shechitah, or an "animal" - that requires both simanim for kosher shechitah. Which leads to a discussion of partial completion of cutting, and how much must be cut to be considered as if it were cut in full for a kosher shechitah. Plus, sourcing "shechitah" in the Torah and the fact that it's done at the neck of the animal. Also, a "drasha" on how an animal's shechitah is kosher, how fish are killed, without a requirement for shechitah, why fowl only require the severing of one pipe, and more. Plus, the interpretations that shed light on the domesticated animals as compared to the non-domesticated animals, which seem to have lesser requirements.
