asking for help... one of my "older hens" about 5yrs, up till last week was laying about 3 eggs a week. Yesterday she was top girl during treat time, but.... This am, she would not get down off the roost, when we picked her up, she had a dirty vent , and did not want to be active. We cleaned her up and gave her an epsom salt bath. During the bath we noticed her breast area is swollen, and feels like she is retaining liquid. (Not in the abdomen like ascites) Any suggestions? This am I separated her into a smaller coop, and this evening, she is still lethargic, and her vent is dirty again.
