UPDATE: My daughter just texted me from the vets office. He said he believes the reason Pipers wing looks like it does, is because the ointment is messing up what few feathers he has left under his wing. He wants us to continue the ointment once a day & wipe down the area with a warm washcloth once a week. He also said he is limping because he sprained his foot, probably when he fell, as he always falls hard to that side & it was just a coincidence. He is going to call & check on him in a week to see how he's doing, but he feels he will be much better in 2 weeks . Personally, I think it looks much worse, but then again his feathers are now always gooped with ointment...
