Mine have haybars and I leave these full when I leave the yard (usually between 5 and 6 pm) and then they get topped up by the person who lives onsite at the yard when they have a last check around at about 8 pm. They are both good doers and one them in particular would eat it all however much you gave him so it probably doesn't last him all night, but he is getting plenty and it won't hurt him to go without for a few hours.
