While most late Karaite writers tend to permit them, several early Karaite
writers forbade them (e.g., see Yehudah Hadasi's Eshkol HaKofer, Alef Beit
233 [page 89 in the 1836 Gözlöv/Yevpatoria edition]). There are only four
mentions of eggs in the whole TaNaKh. The first one (Devarim [Deuteronomy]
22:6-7) says "Ki Yiqqare’ Qen-Sippor LeFaneikha BaDerekh BeKhol-‘Es O ‘Al-HaAres
Efrohim O Veisim WeHaEm Roveset ‘Al-HaEfrohim O `Al-HaBeisim Lo’-Tiqqah
HaEm ‘Al-HaBanim. Shalle’ah Teshallah Et-HaEm WeEt-HaBanim Tiqqah-Lakh .
. ." (If, along the road, you chance upon a bird’s nest, in any tree or
on the ground, with fledglings or eggs and the mother sitting over the fledgelings
or on the eggs, do not take the mother together together with her children.
Send off the mother and you may take the children . . .). Note it says you
may take the children, not the eggs.
