Chapter 3 of 8 in Rest on a Holiday — 17 halachot
Halacha 1א׳
מִי שֶׁהָיָה לוֹ עָפָר מוּכָן אוֹ אֵפֶר מוּכָן שֶׁמֻּתָּר לְטַלְטְלוֹ הֲרֵי זֶה שׁוֹחֵט חַיָּה וָעוֹף וּמְכַסֶּה דָּמָם. וְאִם אֵין לוֹ עָפָר מוּכָן אוֹ אֵפֶר הָרָאוּי לְטַלְטְלוֹ הֲרֵי זֶה לֹא יִשְׁחֹט וְאִם עָבַר וְשָׁחַט לֹא יְכַסֶּה דָּמָם עַד לָעֶרֶב. וְכֵן בְּרִיָּה שֶׁהוּא סָפֵק אִם חַיָּה הִיא אִם בְּהֵמָה אֵין שׁוֹחֲטִין אוֹתָהּ בְּיוֹם טוֹב וְאִם שָׁחַט לֹא יְכַסֶּה דָּמָהּ עַד לָעֶרֶב. אֲפִלּוּ הָיָה לוֹ עָפָר מוּכָן אוֹ אֵפֶר. שֶׁמָּא יֹאמַר הָרוֹאֶה חַיָּה וַדָּאִית הִיא וּלְפִיכָךְ כִּסָּה דָּמוֹ בְּיוֹם טוֹב וְיָבוֹא הָרוֹאֶה לְהַתִּיר חֶלְבּוֹ:
One who had prepared dirt or prepared ash—such that it is permissible to move it—such a one may surely slaughter a wild animal or a fowl and cover their blood. But if he does not have prepared dirt or ash that is fit to move—such a one may certainly not slaughter [them]. However, if he transgressed and slaughtered [them], he may not cover their blood until the evening. And likewise [regarding] a creature [about which there is a] doubt whether it is [classified as] a wild animal or a domesticated animal—we do not slaughter it on the holiday. But if one slaughtered it, we do not cover its blood until the evening—even if he had dirt prepared or ash—lest the onlooker say, "It is a definitely a wild animal, and that is why he covered its blood on a holiday"; so the onlooker will come to permit [that species'] forbidden fat (carried by domesticated animals).
Halacha 2ב׳
וְכֵן הַשּׁוֹחֵט חַיָּה וָעוֹף מֵעֶרֶב יוֹם טוֹב לֹא יְכַסֶּה דָּמָם בְּיוֹם טוֹב. שָׁחַט בְּהֵמָה חַיָּה וָעוֹף בְּיוֹם טוֹב וְנִתְעָרֵב דָּמָם לֹא יְכַסֶּה אוֹתוֹ עַד לָעֶרֶב. וְאִם הָיָה לוֹ עָפָר מוּכָן אוֹ אֵפֶר וְיָכוֹל לְכַסּוֹת הַכּל בִּדְקִירָה אַחַת הֲרֵי זֶה יְכַסֵּהוּ:
And likewise may one who slaughtered a wild animal or fowl from the eve of a holiday not cover their blood on the holiday. [If] he slaughtered a domesticated animal, a wild animal and a fowl on a holiday and their blood mixed together, he should not cover it until the evening. However if he has dirt prepared or ash and can cover all of it with one shovelful, such a one should surely cover it.
Halacha 3ג׳
הַשּׁוֹחֵט בְּהֵמָה בְּיוֹם טוֹב מֻתָּר לוֹ לִתְלֹשׁ צֶמֶר לִמְקוֹם הַסַּכִּין בְּיָדוֹ. וּבִלְבַד שֶׁלֹּא יְזִיזֶנּוּ מִמְּקוֹמוֹ אֶלָּא יִשָּׁאֵר שָׁם מְסֻבָּךְ כִּשְׁאָר צֶמֶר הַצַּוָּאר. אֲבָל בְּעוֹף לֹא יִמְרֹט מִפְּנֵי שֶׁהוּא דַּרְכּוֹ וְנִמְצָא תּוֹלֵשׁ בְּיוֹם טוֹב:
It is permissible for one who slaughters an animal on a holiday to pull out wool with his hand from the place of the slaughter [on the neck]. And [this is] so long as he does not move it from its place but leaves it there entangled with the rest of the wool of the neck. But one should not pluck [the feathers of] a fowl, because that is its customary way; and it would come out that he is detaching on a holiday (according to its legal definition—as opposed to pulling out sheep's wool which does not meet that definition's condition that it be in its customary way).
