Moldy horse hay

Asked February 7, 2020, 10:31 AM EST

Last night, I discovered the hay, stored in the red barn loft, has surface mold on the outside of the bales. No mold at all on the inside, which looks good. This same hay was fine last week. Is it safe to brush or cut off the bad side and spray with vinegar? Don't want to cause colic or any respiratory problems.

I would need to know the color of the mold. For example is it red, bluish green or blue. Maybe even a photo if possible
