I was working in the garden this weekend and had all the chickens out, so I was around them consistently all day. I noticed that several of the chickens had really REALLY loose, wet stool. It litterally sounded like a splash when they did it ... As it was multiple of my birds, I'm concerned there is something going on with my flock! I looked at the stool and didn't see any weird colors or worms or anything like that. Anyone have any ideas or suggestions for me?
