Srtiels, I am using Feather Glo. It is for the prevention of iodine deficiency. The dosage.Add to water daily. Add ten drops per ounce (1 teaspoon per 10 oz. or one tablespoon per quart) of fresh drinking water. Guranteed Analysis: Each fluid onuce (29 ml) (1 fl.oz) contains 9.5 mg postassium iodide. Ingredients: Compound Iodine solution, 1,2,3, propanetriol. None of their seed or pellets have iodine in them. I checked the labels. I have a combination mineral cuttle bone for the two keets to chew on but don't have the ingredients for it. If the cuttle bone comes from a sea creature you would think their would be iodine in it. I know the cuttle bone provides calcium & phosphorus. These two are youngsters about 4-5 months old. As far as getting them to eat carrots etc., we are working on that.
