1. The yellow yolk in the egg provides the chick with food. Layers of egg white, called albumen, cushion the chick and keep it warm. The shell is porous – it allows air in and out so that the chick can breathe!

2. A clutch is the name for a number of eggs that a bird lays in one go. The number of clutches per year changes from bird to bird. The grey partridge lays one of the biggest clutches, with an average of 15 to 19 eggs.

3. The ostrich egg is the biggest in the world. It weighs about 1.5 kilograms – an average hen’s egg weighs only about 50 grams!

4. The smallest egg in the world is laid by the bee hummingbird. The delicate egg is laid in a cup-shaped nest of cobwebs and plants. 

5. The great spotted woodpecker incubates its egg for only ten days. This is one of the shortest incubation periods of any bird. The longest is of the wandering albatross, which incubates its eggs for up to 82 days!
