Daisy is a 2 year old Polish. She has been symptom-free until today. Yesterday, she was free-ranging normally and went to bed on the roost with her sisters + their roo. This morning, I let them out of the coop and, as always, everyone came running, including Daisy. I didn't notice anything wrong with her in the morning. A couple hours later, I found her sitting and not active like she usually is. I've brought her in the house and placed her in the sick chick cage. She drank a little water at first but has not taken anything since. Her lower abdomen is distended. I gently inserted a lubed finger and did not feel any bound eggs in her. She has yellowish diarrhea near her vent. Any ideas? She is a treasured pet and I would really appreciate any advice. Unfortunately, there are no chicken vets or any vets with avian experience in my area.
