I'ts Pox..Like Cynthia said nothing really you can do for this particular bird other than appling Iodine, black Shoe Polish or daub a Magic Marker on the sores to help them dry. Vitamins would be helpful also..You can vaccinate the others to stop any other outbreaks..or let nature take its course and it will slowly go through your flock till whatever bird is going to gets it, and everything will be fine in a month or two unless complicated with the wet form(inside mouth and throat)
If it were me I would vaccinate all the others that are not showing any symptoms..And now that its on your yard and the mosquitos can winter over, You might want to think about vaccinating all hatchlings and any other birds you bring in..
