11 Introduction:
12
13 The aim of the game is to make as much money as possible from your chicken
14 farm. The problem is the foxes, which want to eat your chickens. Since hiring
15 guards is both too expensive and unreliable, the obvious solution is to help
16 the chickens defend themselves.
17
18 Game mechanics:
19
20 You lose if you end a night with no chickens left.
21
22 You win if you survive 14 nights.
23
24 Chickens only lay eggs in henhouses, and must stay on the egg for 2 days to
25 hatch a new chicken. Chickens that hatch in already full henhouses die
26 immediately from overcrowding.
