I wrote a few days ago to say that one of my new chicks had runny poo. I still think that one does. But the one I thought does now appears to have fine, solid poo, though she's definitely not growing nearly as quickly as the others. But someone is still making little runny ones. Someone recommended 1T cider vinegar in a gallon of drinking water. Is this a good thing to do? Their feed is medicated. Thanks!
