What would the Halacha be in a case where one slaughtered a chicken and found 2 tracheas from the mouth to the lungs.

If for example only Rov of one of these tracheas were cut would the chicken be Kosher?

I haven't seen any sources in Halacha that discuss such a case.

  • Is this a theoretical case or does this happen once in while? (like you find animals with 2 heads once in a while)

  • Would it not be a treifa anyway? I guess you can still ask if it's tamei

After discussing this with a shochet, he pointed out that this case is explicit in Shulchan Aruch YD 33:5

וְכָל שֶׁכֵּן אִם יֵשׁ לוֹ שֵׁנִי וְשָׁטִים אוֹ שְׁנֵי קָנִים, דִּטְרֵפָה (תְּשׁוּבַת הָרא״ש כְּלָל כ׳ סִימָן ט׳)

He pointed out, however, that some geese naturally have a forked trachea (near the bottom, where it enters the lungs), and this is considered "היינו רביתייהו" - that's the way it grows, and is not a טריפה. It also seems that in this case both קנים need to be shechted.

There is a general rule in the Halachos of Treifos - כל היתר כנטול דמי - "anything extra is as if it is removed". Basically, if an animal has 5 legs, two of which are connected at the femur, it's as if the entire combination is removed. The removal of the femur of an animal renders it a טריפה. This means that it is prohibited to eat, even if shechted, but it is not טמא.

In a case two tracheas or two esophagus', the rule of כל היתר כנטול דמי would apply, so it would be a טריפה.

    Is there a source that discusses this goose phenomenon? The question is apparently actually more relevant than just tahara

  • here are the sources that my shochet friend gave me: תבואת שור לג:י, כריתי ופלתי לג:י. There is a discussion in a Sefer called "שחיטה ובדיקה בהלכה", which has a number of ספרי שו׳׳ת that discuss it, but I'm not sure how to post a picture here.
