Actually I'm amazed. Her ear has healed wonderfully and there is only a very, very small gap that still needs to heal. She'll have a pretty nasty scar on that ear but honestly unless you're taller than her (and I'm not) you can't even see half of it. Once her forelock and mane grow back they'll cover it partially as well. She appears to have hearing and a wide range of motion in the ear too. The only thing I've noticed that she can't do is flatten her ear backwards, because it sort of healed at a 45 degree angle with part of it flopped over. She can swivel it to listen to things though, which is great.
Makes things interesting for me though! I use a horse's ears to guage what they're about to do or how they feel about new things, and her ear 'language' is MUCH different than other horses because her ear is oddly attached now xD I'm kind of worried that I'm going to misintepret something and get myself hurt!
