Ive had them since april with no ill affects so far but i want a general consensus. My water- has probably the highest iron content in the world(lol) I have a water softener, my family does NOT use a reverse osmosis system. We go tot he local spring and refill 5 gallon water cooler jugs and use a water cooler. This is not feasible for chickens. they use a lot of water. So my question is when i DO have salt in my softener system( i routinely forget to buy it and fudge up my dishwasher and everything) will that hurt the cheekangs? Thanks in advance for any input and/ or help.
