Than you for the additional photos, does his iris look normal? Are you finding discharge/crust in the eye? His eye looks sunken, did he have respiratory symptoms along with the ear infection? What do you mean by they have a head problem? Have you taken a good look at the pupils of their eyes? I would not put any more peroxide on the skin. If it needs to be flushed use saline. I hate to tell you this, but it would be a good idea to trim the feathers away from that skin so you can get a better look at it and it will keep that cleaner when you do get some ointment to put on it. I know you are trying to get them feathered out, nice/healthy etc., so you can re-home them. There are no tricks to get them feathered out. Time and good food will take care of that. I'm sorry you are dealing with this.
