The sons of Rabbi Chiya taught that when performing melika (pinching the neck of a sacrificial bird), the kohen may draw the simanim (the windpipe and gullet) toward the back of the neck and sever them without breaking the neck bone. The Sages dispute whether they meant this is the only valid method (to avoid rendering the bird a treifa by breaking the bone first), or if breaking the neck bone prior to cutting the simanim is also permitted as a Torah-prescribed approach. The Mishna supports this latter explanation.

Rabbi Yannai raises a difficulty against the sons of Rabbi Chiya based on an inference from another line in the Mishna, which the Gemara resolves by demonstrating that an alternative inference can be drawn.

The Gemara notes a debate regarding whether melika can be performed with a back-and-forth sawing motion (holacha v'hava'a) similar to shechita.

Rabbi Yirmia quotes a statement by Shmuel comparing shechita and melika. After analyzing what specific law was being equated, the Gemara concludes that Shmuel is teaching that if one begins the melika too high on the neck (hagrama) and finishes in the correct area, it is disqualified - just as we learned regarding shechita.

Rami bar Yechezkel cites a braita stating that there is no issue with birds if the simanim are found to be displaced. The Gemara disputes whether this applies only according to the opinion that shechita of a bird is not a Torah law, or if it holds true even for those who view it as a Torah obligation derived via halakha l'Moshe m'Sinai.

A further debate ensues over whether Rami bar Yechezkel's braita applies exclusively to melika or extends to the shechita of a bird as well. Additionally, Rabbi Yirmia's statement in the name of Shmuel is presented as a conflicting view to this braita.

Zeira rules that if the neck bone is broken, the animal or bird immediately becomes a neveila (carcass), even if the animal is still convulsing. Rava challenges this: if breaking the neck bone creates a neveila, how could melika ever be validly performed on a bird, given that the process begins by breaking the neck? This would mean the kohen is performing melika on a bird that is already dead. Abaye raises a difficulty against Rava's challenge from the laws of a bird burnt offering, and the Gemara resolves the issue.
