Zevachim8: 5
אֵבָרִין בְּאֵבָרֵי בַעֲלֵי מוּמִין — רַבִּי אֱלִיעֶזֶר אוֹמֵר: אִם קָרַב רֹאשׁ אֶחָד מֵהֶן, יִקְרְבוּ כָל הָרָאשִׁין; כַּרְעוֹ שֶׁל אֶחָד מֵהֶן, יִקְרְבוּ כָל הַכְּרָעַיִם. וַחֲכָמִים אוֹמְרִים: אֲפִילוּ קָרְבוּ כֻלָּם חוּץ מֵאֶחָד מֵהֶן, יֵצֵא לְבֵית הַשְּׂרֵפָה.
5. [If] the limbs [of valid olah offerings became mixed] with limbs of blemished [olah offerings] — R’ Eliezer says: If the head of one of them was offered, all the heads should be offered; [if] the leg of one [of them was offered], all the legs should be offered. But the Sages say: Even if all of them have been offered except for one, it should be taken out to the place of burning.
