What animal laid the first egg?
Back to our original question: with amniotic eggs showing up roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest, it's a safe bet to say the egg came first. Eggs were around way before chickens even existed.
Can a chicken lay an egg with no shell?
But actually, an egg without a shell is often intact. ... You might even think it's a regular egg until you touch it! Chickens need a lot of calcium to create good, hard shells, so most incidences of shell-less eggs in an adult hens are related to not having enough calcium in the diet.

Why is my duck laying eggs without a shell?
HOW DOES THIS HAPPEN – Soft Shelled Eggs or Egg Binding is a common egg-laying associated problem which occurs in female ducks. It is more common in chickens but it also happens to ducks. obstruction of oviposition or cloacal function, due to the presence of the egg in the distal oviduct for longer than it should be.

What are the 5 mammals that lay eggs?
Only five species of animals share this extraordinary egg-laying trait: the duck-billed platypus, western long-beaked echidna, eastern long-beaked echidna, short-beaked echidna, and Sir David's long-beaked echidna. All of these monotremes are only found in either Australia or New Guinea.
Do any mammals lay eggs?
Mammals. As for us mammals, only two types lay eggs: the duck-billed platypus and the echidna.

What are spider eggs?
Spiders make egg sacs that are loosely woven from silk, much like that used to spin their webs. These sacs are typically about the same size as the spider. Other insects, such as moths, also use silk to spin cocoons for their pupal stage. These cocoons closely resemble the egg sacs of spiders.
Did dinosaurs lay chicken eggs?
Dinosaurs were forming bird-like nests and laying bird-like eggs long before birds (including chickens) evolved from dinosaurs. "The egg came before the chicken," Zelenitsky said. "Chickens evolved well after the meat-eating dinosaurs that laid these eggs."
Why did animals start laying eggs?
A Strategic Choice. Early female animals laid eggs in the sense that they released their ova into the world, often thousands at a time. Sperm released by males then fertilized some of these eggs in a hit-or-miss fashion, and the resulting embryos took their chances on surviving in the hostile world until they hatched.
Who came first egg or chicken answer?
Eggs, generally speaking, existed before chickens did. The oldest fossils of dinosaur eggs and embryos are about 190 million years old. Archaeopteryx fossils, which are the oldest generally accepted as birds, are around 150 million years old, which means that birds in general came after eggs in general.
