Cowbirds do that. They follow bison herds to eat the insects that the bison stir up from the ground, but since the bison herd is always moving, the cowbirds lay their eggs in other bird nests nearby, and the foster mother takes care of the chick, even though it's not her own baby.
Nature is so cool.
But barn owls don't do that, so whatever
