White Leghorn Sick!

[casportpony]

Oh, she also always sits on a nest with no eggs in it. All she does is sit there all day. Any ideas why she does that or if she has a disease?

If she sits there all day, it's probably infested with mites, so dust or spray the coop, too.

You should bring her inside after you dust her, weigh her and put her someplace indoors with access to food and water.
