Please help if you can. I'm a new back yard chicken owner. I have four beautiful Polish bantams that are sweeter than kittens. My problem is that one of them has had brown runny diarrea for a month. She acts healthy, eats well, and lays nice eggs. I'm giving her water with cayanne pepper, on the suggestion of another chicken owner, that doesn't seem to be working. I would be so grateful for any suggestions.
