The Torah similarly differentiates between kosher and non-kosher fowl. Unlike animals, the Torah gives no signs to differentiate between kosher and non-kosher fowl. However, since we lack the experience to apply these rules, we are permitted to eat only those fowl traditionally accepted as kosher. All variations of the common chicken are accepted as kosher. Similarly, common domestic ducks, geese's and doves are considered kosher.
Many Sefardic communities have a tradition that the quail is a kosher fowl.
With the appearance of turkeys, Rabbis questioned whether a reliable tradition exists about their kashrus. Common custom today accepts turkeys as kosher fowl . The eggs of any non-Kosher fowl are also forbidden to be eaten. An animal slaughtered improperly or an animal that died in any other manner is a neveilah and may not be eaten. These defects are enumerated on Sinaitic tradition.
