Zevachim6: 5
עוֹלַת הָעוֹף, כֵּיצַד הָיְתָה נַעֲשֵׂית? עָלָה בַכֶּבֶשׁ, וּפָנָה לַסּוֹבֵב, בָּא לוֹ לְקֶרֶן דְּרוֹמִית מִזְרָחִית. הָיָה מוֹלֵק אֶת רֹאשָׁהּ מִמּוּל עָרְפָּהּ, וּמַבְדִּיל, וּמְמַצֶּה אֶת דָּמָהּ עַל קִיר הַמִּזְבֵּחַ. נָטַל אֶת הָרֹאשׁ וְהִקִּיף בֵּית מְלִיקָתוֹ לַמִּזְבֵּחַ, וּסְפָגוֹ בְמֶלַח, וּזְרָקוֹ עַל גַבֵּי הָאִשִּׁים. בָּא לוֹ לַגּוּף וְהֵסִיר אֶת הַמֻּרְאָה, וְאֶת הַנּוֹצָה וְאֶת בְּנֵי מֵעַיִם הַיּוֹצְאִים עִמָּהּ, וְהִשְׁלִיכָן לְבֵית הַדֶּשֶׁן. שִׁסַּע וְלֹא הִבְדִּיל; וְאִם הִבְדִּיל, כָּשֵׁר. וּסְפָגוֹ בְמֶלַח וּזְרָקוֹ עַל גַּבֵּי הָאִשִּׁים.
How was the bird olah offered? He ascended the ramp, turned to the surrounding ledge, [and] arrived at the southeast corner. He would perform melikah on its head opposite the back of its skull, and separate, and drain its blood upon the Altar wall. He would [then] take the head and bring its incision up against the Altar, saturate it with salt, and throw it upon the fires. He would [then] come to the body and remove the crop, and the feathers and entrails which were attached to it, and throw them to the place of the ashes. He would rend but not separate [it]; however, if he separated [it], it is valid. He would [then] saturate it with salt and throw it upon the fires.
Zevachim6: 6
לֹא הֵסִיר לֹא אֶת הַמֻּרְאָה, וְלֹא אֶת הַנּוֹצָה, וְלֹא אֶת בְּנֵי מֵעַיִם הַיּוֹצְאִין עִמָּהּ, וְלֹא סְפָגוֹ בְמֶלַח — כָּל שֶׁשִּׁנָּה בָהּ מֵאַחַר שֶׁמִּצָּה אֶת דָּמָהּ, כְּשֵׁרָה. הִבְדִּיל בַּחַטָּאת, וְלֹא הִבְדִּיל בָּעוֹלָה — פָּסַל. מִצָּה דַּם הָרֹאשׁ וְלֹא מִצָּה דַם הַגּוּף, פְּסוּלָה; מִצָּה דַּם הַגּוּף וְלֹא מִצָּה דַּם הָרֹאשׁ, כְּשֵׁרָה.
[If] he did not remove the crop, or the feathers, or the entrails which are attached to it, or he did not saturate it with salt, any deviation which he makes after he drains its blood, [leaves] it valid. [If] he separated the [bird] chatas, or did not separate the [bird] olah, he has invalidated [it]. [If] he drained the blood of the head but did not drain the blood of the body, it is invalid; [but if] he drained the blood of the body but did not drain the blood of the head, it is valid.
