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 finder. 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 שֶׁחַיָיב 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 them. But not if a public road interrupts between them. This is learned from that, and that is learned from this. This is learned from that: if there were two, he has to make it public. That is learned from this: if there were three, it would belong to its finder.
