Hello all, new poster here although I've lurked for the last couple of years. I have two separate flocks and a singleton hen that just appeared a couple of months ago. She's not fitting in with the mature birds so she just ranges the property by herself. She looked "homeless" when she first came but with proper nutrition she's looking sleek, glossy and has filled out some. My question concerns pieces of something that are about an inch long that I find in her water bowl. They appear to be segments of something. I wormed her with Wazine but these come from her mouth. Once I did see some string or thin rope -- there's just no telling how that came about. But I continue to see these segments of something else. At first they were brown but today's findings were sort of light gray. I'm glad the other birds don't interact with her. I would love to know how to treat this hen. Thanks in advance for advice or suggestions.
