I have three 6-week old chicks and one has water stool, like clear water with bits of poo in it. In fact, the crate has a wet floor where she is most of the time. She is active, bright eyed, except for this water/poo, you can't tell her apart from the others-very active, What could it be? What do I do? They have only been on the patio, never on dirt. There may be an odor OR not involved. Crop is empty.
