Reply To: Eggs

If you only eat the yolks or only the whites, do you save the other for another time?

Like yolks to make custard sufganiyot filling? Or whites to make an egg-white omelette another day?

If not, is it halachically permissible to throw this “food” away?

Maybe birds will eat it if you cook it. Chickens and ducks will eat their own eggs if you throw them on the ground.
