My son went to shut the chickens in and found one lethargic and then just toppled over. We brought it inside, however it keeps closing its eyes, we think it won't make it. Then my husband told me he spread some 'ice melt' down near them earlier. I think I know the answer to this, but I will ask it anyway.....do you think this is probably what killed my chicken? I looked it up, and it said that too much salt can kill a chicken. I think this is probably what happened.
