Mammals have warm blood and give birth to live babies. Some reptiles give birth to live babies, but only because they hold the eggs in their bodies until they hatch. But they have cold blood. Mammals nurse their babies, unless they are humans and feed their babies formula out of bottles. The term "mammal" means "milk-producing", and breasts are known as mammary glands. They're specialized sweat glands. Mmmmmm!
Poultry (food birds but not game birds, like pheasants) are warm-blooded but lay eggs. They have sex and the bird sperm fertilizes the bird egg but the baby bird grows in the egg outside the mother bird. But birds lay eggs even if the eggs haven't been fertilized (meaning they didn't have sex, so there was no sperm to mix with the egg material to make a baby bird.) These eggs are sterile--if a bird incubates them, no baby birds will hatch out. Birds do not nurse their young--they feed them stuff out of their mouths (regurgitated goop or bugs or whatever.)
Sterile eggs should be removed from pet birds or poultry as soon as possible. They will not form babies and will merely spoil after a while. Unattended fertile eggs will also spoil if they're left out.
Monotremes (duck-billed platypus) lay eggs but are warm-blooded and nurse their young.

Yes, all animals mate. The only thing I can think of is that some species of worms can mate with themselves (I think this is true). Do you know there are several animals that are mammals that nurse their young and also lay eggs? Read about the platypus:
http://en.wikipedia.org/wiki/Platypus
Lizards and other reptiles and amphibians (frogs, toads, salamanders) also lay eggs. If there is no male available, they still lay unfertilized eggs. But yes, they all make whoopee, especially if they listen to Johnny Mathis or disco music!!

Animals that lay eggs are females. Chickens are girls, roosters are the boys. If there's no rooster, the eggs are just eggs. If you have a rooster, you may have chicks hatching soon. All animals have a sex, you'd have to get very low on the chain to find one that doesn't. Even worms have a sex - although they have been known to change it if need be.
