A chick that was born on a holiday is prohibited [to eat on that day] because it is muktseh. But a calf that was born on a holiday—if its mother was earmarked for eating—is permitted, since it is prepared by way of its mother. [For] if one were to have slaughtered it's mother [while it was still inside], this [fetus] that was inside would have been permissible on the holiday—even though it was not [yet] born.
Animals that go out and graze outside of the perimeter and come to sleep within the perimeter are surely prepared [for the holiday]; so we may take from them and slaughter them on the holiday. But we may not slaughter on a holiday those [animals] that graze and sleep outside of the perimeter—if they come [within the perimeter] on a holiday—because they are muktseh and the minds of the people of the city are not on them (to eat them on the holiday).
And likewise a consecrated animal that acquired a blemish on a holiday: Since [the owner] did not have his mind on it (to eat it on the holiday) from the eve of the holiday—it is prohibited to slaughter it on the holiday. Therefore it is prohibited for one to examine blemishes on consecrated animals on a holiday, [as a] decree lest the sage permit them (to be slaughtered for personal use) due to their blemishes and [the owner] will come to slaughter it on that [holiday]. But [the sage] may look at the blemish on the eve of a holiday and permit or forbid it on the morrow.
A firstborn that was born [on a holiday] together with a blemish is considered to be prepared, but it should not be examined on the holiday. However if one were to transgress and see its blemish, examine it and permit it—it can surely be slaughtered and eaten. [In a case of] a firstborn that falls into a pit: One should provide its sustenance for it in its place (so that it will not die). For one is surely not able to bring it up, since it it not fit for slaughter on the holiday. [In a case of] 'it and it's child' that fell into a pit: He should bring up the first in order to slaughter it, but not slaughter it. And [then] he should act craftily and bring up the second in order to slaughter it. And he [then] slaughters either one of them that he wants. Because of [the commandment to prevent] the pain of animals, [the Sages] permitted acting craftily [here]. An unconsecrated animal that fell from a roof and survived for [twenty-four hours] and surely [still] requires examination (to determine if the animal is permissible to eat) may be slaughtered on the holiday and [then] examined—[for] it is possible that it will be found fit and may be eaten.
Geese, chicken, and doves in the home are surely prepared; so they do not require setting aside (for use on the holiday). But doves of a dovecote, doves of a loft and birds nesting in pitchers, in a building or in an orchard are surely muktseh. So it is necessary to set them aside from the eve and say, "I am taking these and those." But he need not shake [them].
