I have 2 Speckled Sussex hens that are less than a year old. They have been laying one egg each for some time now. Yesterday I noticed that one of them, Greedo (the one that is usually noisy and running around most) is being really quiet. Usually when I come out the back door they both come up to investigate, but she has just been sitting under the deck. She stayed under there all day yesterday (they usually sleep together on the deck or in their coop) until I got her out and put her in her coop with the other one. The calmer one, Basil, is acting completely normal. Greedo is not eating, drinking, or laying and she has poop all over her underside. They don't usually poop on themselves. What could be wrong with her?
