i have a 5 day old chick with a slight bump above her vent. She has problems with pasty butt, and I am keeping her clean. I read on another thread that witch hazel helps with the protruding tissue around the vent. I have begun applying it. My question: Is witch hazel toxic to chicks? As soon as I finish cleaning and applying the witch hazel, she preens her rear end. I know she has to be ingesting some of the witch hazel I just applied...
