I have thought long and hard about this and come to the conciliation of “the egg” and hears why. This theory requires the existence of evolution.
In the past you had a dinosaur (we will call him BOB) (which are believed to have evolved in to birds) and it laid an egg...

The egg came first because eggs were around long before chickens.
Chickens evolved from non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced the zygote. These changes and mutations only have an effect at the point where a new zygote is created. That is, two non-chickens mated and the DNA in their new zygote contained the mutation(s) that produced the first true chicken. That one zygote cell divided to produce the first true chicken.

Egg came first. Technically, the egg came at the point where sexual reproduction evolved and we got egg and sperm. Remember that not all eggs are hardshelled.

Egg. We've got non-birdlike dinos with fossilized eggs.

Now that creature will lay and egg and the genetic change this time will cause the egg to contain the DNA of a chicken.

How on earth can a dinosaur lay an egg containing a chicken or a bird. That is absurd. I have never heard of a reptile laying an egg that has hatched something with wings, it is illogical.
