We have well water that is a REALLY good well and we use it for drinking and cooking. The way I have he system set up is from the house it goes into an inline filter, then the water softener, then another inline filter to the rest of the house. At the kitchen sink I have a reverse osmosis (sp?) system for drinking. I have been giving the chickens the water from the sink (not the reverse osmosis drinking water) which is softened and was wondering if I should be giving them the water straight from the well before the water softener? I have read many posts about watching how much salty things you give the chickens and that made me wonder about the softened water. So far everyone has been doing fine with it. The filters for the reverse osmosis are too expensive, so don't think that they are going to get the premium water.
