My first forum and new chicken owner. I noticed my chicks trying to dustbathe on a towel (not outside yet) which at first seemed fine. Then today they wanted to do it more than usual and I noticed black specs around the towel and in their feathers. The black specks were not moving and it looked more like black dirt specs. They are scratching their face and have ruffled feathers on occasion. Not seeing eggs or moving creatures so what the heck is going on?
