Do all birds lay eggs?

Yes, as you've already heard, all (female) birds lay eggs. I think I would be scared if any bird didn't...

And, for the answer to your question...

The dinosaurs came first. All birds evolved from dinosaurs/related reptiles.

RE:

Do all birds lay eggs, and which birds do? Which came first, the bird, or the egg?

Only female birds lay eggs.

The egg came first.

Yes, all birds lay eggs, only sometimes the female will lay it while asleep, and it just might crack open during the night, and she doesn't know it. Try looking at the bottom of the cage every night for a couple of weeks.

Actually, scientists believe that, since Adam and Eve started out fully grown, the bird probably came first. There is no true and clear evidence, though.

only female birds lay eggs

Only female birds lay eggs... and the bird came first.

The answer is "no" all birds do-not lay eggs.

It is only the Female of the species that "Lay" eggs.!

I just want to comment on another poster's comment:

"Actually, scientists believe that, since Adam and Eve started out fully grown, the bird probably came first. There is no true and clear evidence, though."

I think you're confusing scientists with creationists. Science does not support the Adam and Eve myth.

And there is some pretty true and clear evidence; it's called evolution. Look it up.

Only the hens, the proverbial question has no answer. I may suggest the religious section ,they have all the answers.

that is an interesting question I hope you will get valuable answers
