All birds have feathers - a beak - no teeth - lay hard shelled eggs
Reptile eggs are soft-shelled - as opposed to the calcified shell of a birds egg.
Birds lay normal, hard-shelled eggs while reptiles usually lay eggs with a leathery shell that is flexible.
The eggs laid by monotremes (egg-laying mammals) are still called eggs. They are soft-shelled and leathery, rather than hard-shelled like birds' eggs.
No, they lay eggs but the eggs they lay are hard-shelled, like a birds eggs. For example, crocs lay eggs and when they hatch the baby crocs just pop out o their, lyk they do when yr watching cartoons!

yes birds lay eggs
No. Most reptiles lay eggs, as do most amphibians, and many species of fish. There is even a subgroup of mammals known as monotremes, which lay eggs. This group is made up of just the platypus and the echidna. Insects, arachnids and many invertebrates also lay eggs.
