Chickens are like ground vultures. They will scarf most any corpse they encounter, even a snake. A chicken has found a dead snake and the race is on to find a quiet spot where she can feast on it without being disturbed by the other chickens.
So would a chicken kill a snake? Some chickens do. Chickens are accomplished hunters. If they see something small and moving, they won’t hesitate to nab it with their beak. They can move with astonishing speed. These descendants of dinosaurs are formidable. If you close your eyes when they scream, you can hear a Velociraptor screaming.
