אֶפְרוֹחַ שֶׁנּוֹלַד בְּיוֹם טוֹב אָסוּר מִפְּנֵי שֶׁהוּא מֻקְצֶה. וְעֵגֶל שֶׁנּוֹלַד בְּיוֹם טוֹב אִם הָיְתָה אִמּוֹ עוֹמֶדֶת לַאֲכִילָה מֻתָּר מִפְּנֵי שֶׁהוּא מוּכָן עַל גַּבֵּי אִמּוֹ וְאִלּוּ שָׁחַט אִמּוֹ הָיָה זֶה שֶׁבְּמֵעֶיהָ מֻתָּר בְּיוֹם טוֹב אַף עַל פִּי שֶׁלֹּא נוֹלַד:
A chick that was hatched on Yom Tov is prohibited [to eat on the Yom Tov it was born] because it is Muktzeh. A calf that was born on Yom Tov- if it's mother was going to be used for meat- it is permitted [to slaughter the calf and eat it on Yom Tov] because the animal is considered to be prepared [for Yom Tov] because of its mother's [status] and if one were to slaughter it's mother while it was still inside- it is permitted to eat [the fetus inside] even though it was not born.
