The electricity is conducted in tissue or organism due to the high concentration of electrolyte contents such as potassium, sodium and also many polar biomolecules (usually very weak). Hence, chicken can conduct electricity like all of us can. However, conductivity can vary depending on the contact. It may conduct more if it is probed deep into the tissue with a wet contact. You can measure conductivity using simple arrangement of probe and a multimeter or resistance meter.
