12. Activity 2 – Life Cycle
Farmer Dylan placed some hens and cockerels together in Pen
A. In Pen B, he kept only hens. Several days later, he noticed
that the hens in both pens have laid eggs. A few weeks later, he
noticed that the eggs in Pen A have hatched into eggs but not
those in Pen B.
Explain to Farmer Dylan why this has happened.
How long does Farmer Dylan have to wait for the
egg to hatch?
If Farmer Dylan wanted to rear eggs for eating
only, what must he do?
