So I've always boarded my horses at a place where hay is either provided or I buy from the barn owners hay supplier. However I recently moved my horses to a barn where we need to find our own hay supplier. I didn't really like the last hay supplier as it was hit or miss whether I would get decent hay or not (either weedy, moldy, dusty bales were mixed in with good ones).
What are some things to ask possible hay supplier? I really don't know much about hay... is a first cutting good or bad?
I know to ask for : was it sprayed for weeds, stored out of the rain... anything els?
