I have one leghorn hen a few years old, who was laying fine until she started having very watery droppings. They seem to vary in color, but always very watery Of course, she has stopped laying completely and has continued to have watery droppings virtually non-stop for many months now. She eats fine and seems to have reasonable energy although she is rather thin (I think most leghorns tend to be on the lean side anyway). None of the other 9 hens in our backyard (pets) flock seem to have picked up her problem, as yet. I have tried a number of medications. I thought it was coccidosis, so I tried something for that (can't remember what it was though). That didn't seem to work. Then I thought maybe its was worms, so I tried piperazine (or something that sounded like that). That didn't seem to do the trick either. Any thoughts on what I should try or re-try (Maybe I did not administer the other drugs long enough). I hate to see her with a soggy bottom every day and no doubt its not good for her in the long run.
