We have a small Dominique that's about 1 1/2 years old. I don't think she has ever laid an egg. Several months ago she started looking sickly, and we noticed that her tail feathers were always wet with feces. My husband picked her up and we noticed that the opening to her vent was all crusted up and was very small. We soaked her rear in warm water and scraped off the dried on stuff. She seemed to look alot better. She always eats and drinks well, but usually keeps to herself. Recently we've noticed the coloring in her face turning to a pale almost grayish color. We still don't think she is laying. We wormed once with Wazine last year, but don't like discarding the eggs, so we've recently tried garlic and cayenne. Any clue as to what can be wrong with her?
