When I first saw her I thought they had spread over most of her body. After I got my hands on her I realized her coat is just full of static and so parts of it are sticking up and parts are flat. Phew. However, her face has more bumps on it tonight than it did last night or this morning. A friend brought up bedding being a possible source so I pulled out their bedding pellets. I've stopped the smartgut ultra, the turn out, and now the bedding. She's getting the same grain she has been on (same bag even), the same hay etc. Hopefully I can pinpoint the cause and they will go away as quickly as they came on.
