UPDATE: She's passed away... I'm gonna copy and paste the post I put on FB last night, but if anyone could help, it would be great. "Sick chicken! I have a Leghorn that is 3 years old. Today my daughter noticed she was pretty lethargic. I wasn't home, so I wasn't able to do anything for a few hours. So, now I'm home with her and she looks pretty bad. She doesn't appear sick. Her eyes are clear and her lungs sound clear. Her abdomen is soft and her breath smells normal. The only symptoms she has are lethargy and her comb is pretty warm. I was able to get some water down her with Sav-a-Chick in it. I'm not sure if she's gonna make it, but I'm also worried about the rest of my flock. Any help would be greatly appreciated!" Update: She pulled through the night, and her comb isn't quite as warm. She's also holding her head up.
