Press the green flag to start. press the packet in the bottom-left corner to buy more eggs. If you have no chickens left and not enough money to buy one, you will automatically get 2 eggs. The eggs will grow into hatchlings, then chicks, then either hens or roosters. If you have both a hen and a rooster, they will lay eggs on their own. You cannot have more than 15 chickens at a time. Chickens will also die, faster the more chickens there are. You can also sell chickens, for more money the younger they are. Money comes in the form of G, which stands for Gold. Hens give more money than roosters. Enjoy your farm!
