Actually I have no idea. At first it started as a few small balding spots that I figured were from flys laying eggs there. So I put her mane up. That only seemed to make it worse. It has spread down her neck and is grey and crusty and ew. Now im thinking ringworm. The vets came out today and said they have NO IDEA what the heck it is but took some cultures and bloodwork.
If your horse has had like...any skin isues like rainrot exema mange ringworm etc. tell me a little bit about what it looked like..and what you did to treat it just so I kinda know.
