Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
Hard shell eggs.
Birds and mammals both evolved from reptiles.
Birds lay normal, hard-shelled eggs while reptiles usually lay eggs with a leathery shell that is flexible.
Reptile eggs are soft-shelled so that the babies can break out of the shells. Bird eggs are hard-shelled, because baby birds use their beaks to crack the shells of their eggs, but since reptiles don't have beaks to use to break their shells, their eggs have to be soft-shelled.

In North America, cowbirds do this. In Europe, it is a type of Cuckoo that does this.
