Hello there, sorry for the delay in response. Lactation in a non-pregnant mare can sometimes happen from digesting phytoestrogens in certain types of pasture/hay, one in particular is white clover. I would suspect that maybe there is something she is digesting from her hay or pasture that is causing this, especially since she has nursed a foal in the past, that can make them more prone to this. In general you can just ignore this, but if she is uncomfortable, I would be concerned that she could be developing mastitis. If the bag is warm and painful to the touch, or if she develops a fever, have your veterinarian evaluate her asap. Otherwise if she is just uncomfortable but not sick, you may want to change pasture or look closely at your hay and possibly switch to a different type, such as grass hay only (timothy, orchard), with no alfalfa/ clover/legume hay in it.

I hope that helps, let me know if you have any further questions or concerns,

Dr Emily Weaver
