My chicken, a one year old RIR, looked as though she was struggling to lay, we were concerned that she was egg bound (fluffed up, and dropped butt like she was going to poo). She started acting "funny" at 4pm, and went in the nest box around 6pm. We had already tried lubricant and checking her cloaca around 5:30, to see if there was an egg stuck. We went to town around 6:00, and came back just now (9:45) and there is some yellow yolky slime and a membrane that looks almost like the finger of a latex glove. She looked really uncomfortable, and is still in the nest box. What do you think? Help!
