וַיֶּחֱמ֥וּ הַצֹּ֖אן אֶל־הַמַּקְל֑וֹת וַתֵּלַ֣דְןָ הַצֹּ֔אן עֲקֻדִּ֥ים נְקֻדִּ֖ים וּטְלֻאִֽים׃
Os rebanhos concebiam diante das varas, e as ovelhas davam crias listradas, salpicadas e malhadas.
Rashbam on Genesis
ויחמו הצאן, this is a masculine construction.
Radak on Genesis
ויחמו, a reference to the males. However, as we learned earlier, the females would be in heat simultaneously.
