Jerusalem Talmud Bava Batra 2:6

משנה: נִיפּוּל הַנִּמְצָא בְתוֹךְ חֲמִשִּׁים אַמָּה הֲרֵי הוּא שֶׁל בַּעַל הַשּׁוֹבָךְ חוּץ מֵחֲמִשִּׁים אַמָּה הֲרֵי הוּא שֶׁל מוֹצְאוֹ. נִמְצָא בֵין שְׁנֵי שׁוֹבְכוֹת קָרוֹב לָזֶה שֶׁלּוֹ וְלָזֶה שֶׁלּוֹ. מֶחֱצָה עַל מֶחֱצָה שְׁנֵיהֶן יַחֲלוֹקוּ. MISHNAH: A pigeon chick which is found within 50 cubits belongs to the owner of the dovecote; farther away than 50 cubits it belongs to its finder⁷³It is axiomatic that a pigeon chick which cannot yet fly does not move farther than 50 cubits away from the dovecote. Therefore, any chick within 50 cubits belongs to the owner of the dovecote; the rule prevents property disputes about pigeon chicks.. If it was found between two dovecotes, if it is closer to one of them, it belongs to it; in the middle, both [owners] shall split evenly.

הלכה: נִיפּוּל הַנִּמְצָא בְתוֹךְ חֲמִשִּׁים אַמָּה כול׳. הָדָא דְתֵימַר. בְּשֶׁאֵין דֶּרֶךְ הָרַבִּים מַפְסֶקֶת בֵּנְתַיִים. אֲבָל בִּזְמַן שֶׁמַּפְסֶקֶת לֹא בְדָא. הָדָא יַלְפָּה מֵהַהִיא וְהַהִיא יִלְפָּה מֵהָדָא. הָדָא יַלְפָּה מֵהַהִיא. שֶׁאִם הָיוּ שְׁנַיִם שֶׁחַייָב לְהַכְרִיז. וְהַהִיא יַלְפָּה מֵהָדָא. שֶׁאִם הָיוּ ג̇ שֶׁהוּא שֶׁל מוֹצְאוֹ. HALAKHAH: “A pigeon chick which is found within 50 cubits,” etc. That is, if no public road interrupts between them⁷⁹This refers to the last case in the Mishnah, if the chick was found between two dovecotes less than 100 cubits from one another.. But not if a public road interrupts between them⁸⁰One may assume that the chick was lost by a passer-by who gave up hope to recover it; therefore, it belongs to the finder. (Babli 23b/24a).. This is learned from that, and that is learned from this⁸¹“That” is Halakhah Bava meṣia‘2:4, Notes 54–55. Something found in an apartment shared by two people has to be advertised; in a hotel frequented by 3 or more people it belongs to the finder.. This is learned from that: if there were two⁸²Dovecotes within 50 cubits of the chick., he has to make it public. That is learned from this: if there were three⁸²Dovecotes within 50 cubits of the chick., it would belong to its finder⁸¹“That” is Halakhah Bava meṣia‘2:4, Notes 54–55. Something found in an apartment shared by two people has to be advertised; in a hotel frequented by 3 or more people it belongs to the finder..
