I came home from a 10 day vacation (I'm not sure how long this illness has been going on) to see my New Hampshire hen looking a little off. She still goes out with the others, but she lays down a lot and isn't her usual bossy annoying self. When she walks she has her normal posture. She just looks 'off'. Her comb is very pale and I saw her poop a very watery poop this morning. Her crop feels a little squishier than my other girls this morning as well. Any ideas on what it is and how I should treat it? I'm going to separate her later today if I can find somewhere to put her so I can monitor her food/water intake. Also, she is still laying.
