So my Andalusian pullet has plucked back feathers on my spotted Sussex, dark Brahma & buckeye. The Sussex is bad Ive been cleaning it with vetericyn plus then putting Hen healer multi purpose ointment on it. Am I doing the right thing? The perpetrator is in a separate bin in the garage and the Sussex is in a room in the house.the other two injured are healing already and out in the coop with the other pullets.
