# Example animal (D19/D23: GrowthSystem reuse — no animal system). Chicken
# advances through stages exactly like a crop: feedRequired replaces
# waterRequired (the animal must be fed via GrowthSystem.feed / animal.feed to
# advance a feedRequired stage, and to produce while mature). The produce table
# is data only — the egg is actually granted by behavior-language content that
# hooks the animal-produce event (see content/statemachines/chicken-egg.yaml).
