I just got home from church and my *** husband was draining the pool for winter right into my chickens lot. There was a pool of water in there. Our pool runs off of a salt filter,so it is mostly salt with a smaller amount of chlorine then normal pools. I got them locked in their house, but You know how chickens are, I"m sure they drank it. Will it hurt them??? What can I do or give them to help clean it out of their systems??
