Study Guide Beitzah 23 Today’s daf is sponsored anonymously in memory of Batsheva Esther bat Yosef Shalom, Rebbetzin Batsheva Kanievsky. The Gemara discusses different opinions and different laws related to burning aromatic spices in other to produce scents on Yom Tob. Rabbi Gaviha permitted ketura. Ameimar wants to understand what ketura is and Rav Ashi answers him that it is smoking fruits and is permitted as it is similar to putting meat on coals. The rabbis forbade eating a goat mekulas (roasted in the way the Pesach sacrifice was roasted) on Passover night because it will cause people to think that after the destruction of the Temple, people can eat sacrificial meat outside of Jerusalem. The Mishnah lists three things that Rabbi Elazar ben Azaria permitted, even though the Sages did not. He permitted for a cow to go out on Shabbat with a decorative strap between its horns and did not forbid it because of the requirement for animals to rest as well. He permitted one to comb an animal on Yom Tov with a fine comb to remove ticks and lice. And to grind pepper in its mill. Rabbi Yehuda forbade combing an animal with a fine comb and the rabbis forbade it even with a thick wooden comb. What is the basis for the dispute between the three? The Mishnah explains the laws of impurity to the three parts of the mill - and why each part is susceptible to impurity. The Mishnah speaks of laws related to a child’s wagon in matters of impurity, of carrying it on  Shabbat, and also in the matter of dragging it on the ground on Shabbat. The third chapter begins with a discussion of trapping on Yom Tov -  when it is permitted/not permitted to trap fish/birds/animals on Yom Tov.
