I think it is hard to say, as I think we all are using fodder differently. I am using it as a supplement to layer feed, so not very much. If you use it as the main feed, then I would guess at least a couple ounces of dry seeds (before soaking) for each hen per day. But that is really a guess. I figured that if a hen eats about a quarter pound of dry feed a day, then you would need half of that in dry seeds. You could start with some larger amount and adjust downward.
