We have just come home from vacation; my neighbor has been watching my chickens for me. This morning the rooster has open wounds on upper feet/lower leg area. Starts at the bottom toe and moves to just above the spurs on both feet (only on the backside). It looks as though all the scales/skin has been removed from this area. Do you think it could have been an animal attack of some sort? Any other ideas? He is limping but seems okay otherwise. Treatment recommendations would be appreciated, as well.
