Like most eggs they would be softish when they were first hatched but exposure to the air makes them hard.
Well, the eggs have soft thick shells so if they drop the egg(s) they will bounce.
a dinosaur egg is a egg that dinosaurs make
No they do not have soft shells
Big dinosaur, big egg. Small dinosaur, small egg.
Turtle eggs (and tortoise eggs) can be either hard or soft-shelled, depending on the species.
Depends very much on whether is "looks like" a dinosaur egg or IS a dinosaur egg. A dinosaur egg, after all, looks quite a bit like a rock.
You can sell soft Taco shells.
Their shells are soft because they start to shed their shells.
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.
Adding calcium/ crushed shells to their diet will help, you can also buy a water soluble tonic to add to their water that will give them the optimum amounts of vitamins and mineral they need to produce hard egg shells. Young hens will produce the hardest egg shells and older hens at the end of their laying years will often start to lay soft/ rubbery eggs.
Egg
The dinosaur egg always comes first. Every dinosaur starts is life as an egg. It is like asking what comes first birth, childhood, adulthood, middle age or death.
