Well then I must be starving my horses because the only one that gets grain is my baby. Not every horse needs grain. If they have good forage and are doing nothing more than light work, forage is sufficient. Not every horse needs 50 different supplements and a bucket of concentrates a day.
My point is that it is not always low feeding that causes thinness- it is many times an underlying medical condition. Before you assume a person is starving their animals, have a vet check done. =)
Spent a whole hour today laying in a pasture, waiting for a sparkling vampire to show up. Alas, I woke up and looked over, only to find a mound of horse crap. Sigh.
