I need help! One of my hens became very lethargic and was having watery poop. I put her in the basement to isolate her from the rest of the flock, gave her some antibiotics in her water and she has perked right up, but still has a very wet vent with clear drainage. The rest of the flock seems more loose than normal, but maybe I'm just looking harder. What do you suppose it could be and what should I do about it?
