The eggs you buy in the store come from female

chickens, which are called hens. But hens are not the

only animals that make eggs. In fact, many other

animals lay eggs.

Eggs come in many sizes, just like the animals that

make them. You need two hands to hold an ostrich egg,

which can weigh up to three pounds! That makes sense

because an ostrich can be more than six feet tall and

weigh three hundred pounds.

A hummingbird’s eggs are quite small. They are

only as big as your fingernail. As you might guess, a

hummingbird is tiny. It should come as no surprise that

insects lay really small eggs.

Animals lay their eggs in different ways, too. Some

lay their eggs one at a time. Others lay large batches

of eggs at the same time. A spider might lay hundreds

of eggs in an egg sac. A frog lays its many eggs in long

strings of jelly in the water. Fish lay groups of eggs that

can either float or sink. Sea turtles fill sandy holes with

hundreds of eggs.

Not many mammals lay eggs. Mammals are animals

that have fur and are warm-blooded. Only two mammals

lay eggs. One is the platypus, and the other is the

echidna. These unusual animals are found in Australia

or New Guinea.

Eggs come in all colors, too. Chicken eggs are an

example of this, and they can be white, brown, blue,

or green.

Animal eggs are an enjoyable topic to study. The

animals that lay eggs are interesting, and they live in

all different parts of the world. Their eggs are as unique

as the animals that make them.
