Care for your chickens. Expand your island. Breed chickens of multiple colors.

Expand your island to sustain a larger flock of chickens.
Chicken Genetics. Each chicken has its own genetics that determine its color. Breed your chickens to create many different colors.

Sell eggs and chickens to make more money to spend on expanding your island.

Be careful that your flock doesn't grow too large. Have too many chickens and they will eat everything growing on your island. Manage the size of your flock to prevent mass death.

No hard limit on the number of chickens. Only limits are your ability to care for them and your devices performance.
