A- get them replaced, no questions asked..... B- the guy when baling needs a moisture stick to measure the moisture content. then he knows- cows or horses. But we cut our hay later in the afternoon- lower sugar content. we toss our wind rows twice, so the hay is turned over on 3 sides to dry and then we bale in the afternoon too(2-3 days later). Hay has to be dry, if not , you are asking for problems, just picture this. a moist bale of hay in the barn can release mold spores into the barn like you could never imagine. There was a single bale in our barn that set Duke's allergies off. it was a night mare. hate to say, our hay is stored in another barn and I get a wheelbarrow and wheel it into the stall barn when it is fed.
