why chickens cant fly?
Chickens can fly for short distances. In the wild, they roost in trees, not on the ground. Chicken farmers will "pin" their wings to keep them under manageable control. "Genetically-modified" chickens are raised for human consumption, and are not structurally the same as wild birds. Normal chickens can fly pretty well, and banties can fly as well as partridges! (i.e. not as high or as far as migratory birds).
