Reply To: Why do regular ol’ chicken eggs need a hechsher?

There is a Rema that says that a test for bird kashrus is to put the bird on a wire, and see if it splits its claw with 3 toes on one side, and one on the other, or two and two. Modern egg laying chickens sometimes walk with two toes in front, and two in back. That’s where the shayloh comes from.
