One of my poor Plymouth Rocks has been sick for about a week now, and i am not sure what she has, or how to treat it! Her face is usually a bright pinkish red, but is this pale whitish, pinkish, yellowish color. She has been having very bad diarrhea, the entire time, and has lost a lot of weight. She does eat, just not very much, and her "food pouch" has been empty for way too long. I don't know whether she has a worm/worms or whether its just a virus. Her condition is not getting worse, but I am worried for her! If you know anything that could help, please let me know!
