Last night at feeding I noticed some welts on the new mare. The other 2 horses were fine. This morning she had them all over her body. She doesn't seem bothered by them except that she is a little lethargic (but she has been that way since I brought her in last week and I chalk it up to acclimating and/or personality). All three horses are turned out together and eat the same food. Some of the welts are hard. Someone suggested ants but I don't see any evidence. Any ideas? (BTW, one horse just got over strangles - 2 weeks past the outbreak).
