I have a 4 month old runner duck that has stopped eating. Her poo is white and runny, and dot very often either. It is very wet here(Louisiana, in the flooded area!) and she always has her beak in a mud hole. I have her in her pin today and away from the chicks and mud holes. I put electrolytes and probiotics in a bowl of water for her. She doesn't move much at all, not quacking (she usually is very vocal). Im thinking a bacteria from all the stale water. Any ideas? She is pitiful.
