A. OK, I see where you get that from. The verse says “Don’t cook a kid in its mothers milk.” So you infer from that sentiment that a chicken and egg would be the same. But classic Rabbinic interpretation in the Talmud doesn’t explain the verse that way, therefore chicken and egg is fine and 100% Kosher. In fact, there would be no shnitzel if you couldn’t soak a chicken first in egg and then in breadcrumbs or matzah-meal.
