3 days ago I realized that my chicken, my avatar chicken, started to have a stream of yellow diarrhea reaching down her vent. I looked in the coop and saw also some yellow diarrhea. She is eating and drinking still with gusto, and still is moving around fine. Her comb, wattles, and face seems to be a lighter color than red. Some of her wrinkles on her face have disappeared. This puzzles me. Today, when I held her, she seemed lighter. I weighed her and she measured 4.8 pounds. Her vent feathers are not falling out and her crop is not swelled. It does not seem to be severe at this point, but I lost two chickens a few years ago which I treated for pasty butt and it did not help. This is my favorite chicken. I am in school and she is one of my only friends. Please reply!!!
