Regarding belt feeders. If a feeder is listed as a 24 hr feeder, and has a capacity of 5#, does that mean that it dispenses up to 5# of feed in a 24 hr period depending on how the feed is placed on the belt? I've never used one or seen one other than a picture. I'm assuming that you pull the belt back to wind it, load the feed on the belt come back 24 hr. later and repeat?
