I have a 9 month old Golden Laced Wyandotte hen, who lives in a large coop with attached covered run with 4 other same age, similar size hens. They free range all day on grass in an acre fenced in pasture. She has seemed to be eating and drinking well, laying normally (every other day for her). No pecking order issues. So, now to my problem. This morning when I opened up the coop, she did not come out. I looked inside, and she was just sitting on the roost- not normal for any of them at 8:00 am! I waited, and she did come out on her own, but just hung out in the run area, not venturing outside. I watched her for a bit, and noticed she seemed to be very lethargic, not attempting to eat or drink, or join her friends. She also seemed to have very runny, yellow-ish droppings, and seemed to be straining to push it out. I had to leave for work, and just returned 9 hours later. She is out in the pasture, but laying down. She doesn't attempt to get up when I go near her, and still looks "dumpy" . She did stand up, and I can tell she has had more runny, yellow-ish droppings. Anyone have any input as to what this might be? And any suggestions for how I can help her out? Thank you in advance.
