My poults are about three weeks old and have developed some sort of problem. I had 6, but one died this past weekend when I wasn't home, so I don't know if it had the same problem 3 others do. They're still eating and drinking, but one cannot hardly walk for keeping it's balance, and two more are trembling slightly when they're moving around, like their legs are weak or unsteady. I vaguely recall something like this affecting young turkeys, but cannot remember what it was. I have a package of vitamins & electrolytes, but am unsure of how much to give them as a supplement. Does anyone know the dosage for 1 gallon? I have other older turkey poults, but they haven't been affected.
