Skin problem ...Little scabs on legs and under chin

[Shadowhills Farm]

Had the same problem- it's a form of rain rot. You need to peel the scabs off, use iodine to clean it out, hose it, use antifungal shampoo and keep that on for 10 minutes and let it dry. It usually goes away after 2 days of treatment. You can also use MTG on it to get the hair growing back.
