Today I walked into the coop area and noticed that "Blue" my Buff Orphington is sick. Her comb is pale and she looked stress. I picked her up and noticed that large clumps of poop were stuck to her butt and her abdomen appears to be distended and squishy. I put her out in the main yard and surprisingly she pecked at the ground and ate some grass. I offered her a tomato and she ate it but definitely not with her normal tenacity. Any ideas on what other clinical symptoms to look for to diagnose her??? I feel so bad for her She was my first chicken and I am upset.
