PAGE 1 OF 5, THE SHELL THAT HOLDS LIFE
CHICK STARTER KIT
AN EGG IS A TINY NURSERY
A chicken egg is built to grow a chick from zero. Inside one shell you find water, protein, fat, vitamins, and minerals. Almost everything a baby bird needs is there. Vitamin C is the famous exception: chicks must get that from their feed after hatching. For humans, that same package makes eggs one of the most useful foods on the planet.
⚡ DID YOU KNOW?
The shell has thousands of tiny pores so air can pass through while the chick grows inside.
CRACK!
SHELL STRONG
🥚 Calcium carbonate makes the shell hard enough to protect the chick but thin enough to hatch.
🎨 Brown or white shells only show the hen's breed, not better nutrition inside.
MEMBRANES
🛡️ Two thin membranes under the shell block germs from reaching the yolk and white.
🫧 The air cell at the round end gives a hatching chick its first breath.
