She was getting much better until a few days ago (she has been with me about three weeks now). She was unable to stand on the bad hoof about three days ago, and was poulticed with Epsom Salt poultice. I took the poultice off yesterday, and there seemed to be a squishy spot up by the coronet band which when pressed, made her flinch and pull back.
Does this sound more like an abscess, or another founder? She's been padded for the last three weeks, poulticed, soaked daily when not poulticed, eating only local grass hay.
