Iris won't come out of co-op..Tail feathers hunkered down..Comb still decent color will eat and drink if I feed it. I have put my index finger in as far as 3 inches but don't feel an egg. Soaking her now Gave her Tums...mostly clear and white diarrhea. Started corrid yesterday.....as I have had coccidyia in the past. It has been moist and rainy lately but all other hens are fine. I really thought she had an egg stuck but I didn't feel anything and had my pointer finger up to the knuckle. Everything seemed clear when I was soaking her. . Such unusal behavior for this chicken.
