Can birds carry their eggs because a bird laid 2 eggs in a nest on my porch in a hanging basket it was there for a week and then i looked and it was gone along with the eggs and there was no shell?

Oh, what a mystery! Birds don't carry their eggs once they've laid them. It's possible that another animal, like a squirrel or a crow, may have taken the eggs for food. Nature works in mysterious ways, but it's important to appreciate the beauty of the cycle of life around us.
