I have a wonderful female muscovy who is sitting on eggs that are due to hatch within a week. I noticed this morning while feeding her, that she has diarrhea. Should I be concerned, or is this something that will resolve itself once the eggs hatch? She and our female pekin live with our 3 chickens. They are let out everyday to free range our yard. Rita (the muscovy) stays on her nest and doesn't leave it. Once I let the chickens and the pekin out, I close the door and Rita could have free range of the chicken house. Her nest is in a large kennel, and I close the kennel door at night when I let the rest of the herd back in. (One chicken, in particular, would like to chase her off so she could sit on the nest) I hand feed her our regular feed every morning and water her. (I have not seen her off the nest since very early in her sitting.) Any suggestions?
