I am a first-time chicken raiser with a sick hen. I noticed yesterday that one of my hens wasn't as energetic yesterday, but didn't think much of it. Today when I went to give the ladies their breakfast mash I noticed that her comb was much, much paler than usual, her energy level was very low (she usually runs away when approached, but today she let me handle her), and that she didn't have much appetite. Her crop seemed empty, though she was standing next to the layer pellet hopper. When I brought the mash she didn't head over for her share as usual. Upon inspecting the coop I noticed white diarehea on the perch, and when I checked the hen she had the same watery white stool streaking the feathers around her vent. My pullets are 26 weeks old, and all have started laying except for this one. at the moment all the others seem fine and happy with normal big appetites. Does anyone have an idea of what might be wrong with my hen, and what I can do? Unfortunatly it is Christmas Day so my vet and store options are minimal.
