As the chicks have been settling in, we did have a case off pasty butt. 3 of the 4 chicks got it and a cleaning we went. They did great as we cleaned them up. I saw where a lady said she used apple cider vinegar to help with pasty butt, so I added a little to their water. Seemed to do the trick for a while. A week later only one of the chicks had it again. But now she is pasty butt free and I've replace the apple cider vinegar with chick electrolyte and vitamin supplement.
