I agree the second full head photo looks much better. I'm thinking the scale loss caused the mark. I would just be sure to keep it clean. If it starts looking worse, put some over the counter antibiotic cream on it. I'm thinking it will clear up fine with no problems.Thanks, the eye is definitely fine, the beak needs a trim, but still not sure about the mark on the ear scale still looks a bit odd but not quite as worrying in that photo. Monitor it closely for a few days and if redness increases or anything that looks worse, get him to a vet.
