I have found that the vitamins in the water every day seems to case them to poop more and make the pasty butt worse. Also sprinkling grit on their food and giving them a finely ground whole grain cereal helps.there isn't much there anymore, still having problems with the poopy butt though
This is the stuff I buy and feed it to all my newly hatched chicks. They love it! The heath food stores carry it and have their own version in the bulk bins also. Feed it dry or cooked. I feed it dry.
