Chicken blood loss sometimes looks like a lot. I would just make sure the bandage is not getting soaked with blood. Pressure on a bleeder for a few minutes will usually clot.
Did you put pressure on the bleeding area? Can you put some Neosporin antibiotic ointment on a gauze pad and tape it on the foot? How is he doing now? Get him drinking some fluids and offer food. Do you have a picture?
