Hello all- My 4 year old BO hen has a full,soft crop. Her appetite has been poor x 2 weeks. She is fed layer pellets, a couple handfuls of scratch every 2-3 days, a few kitchen scraps (pasta, veggies to pick at, leftover bread) every 2 days or so, and free-ranges for 2-4 hours in the afternoons when I am home to help deter hawks. She has liquid green stool. Her body condition has been gradually declining. When I examined her a week ago, she seemed a little thin, otherwise fine. She was eating a little, especially when out free ranging. Today she was depressed, not eating anything, just picking at food and dropping it again. Her toenails were curled under (it was about 30 degrees last night). Other than weight loss, lethargy and a full, soft crop (she regurgitated a small amount of clear fluid while I was palpating the crop) her external exam is normal. I see no lesions in her mouth or on the face. She does have some foul-smelling greenish feces on her feathers below the vent. I can do surgery, I have access to anesthesia, antibiotics, other medications. Should I give her another day, or do surgery today to clean out the crop? From reading Gail Damerow's Chicken Health Handbook, she either has sour crop (thrush) or an impacted crop. How do you tell the difference? Are there other causes of decreased crop/GI tract motility? I have brought her inside in a dog kennel. She has water and no food right now. Thanks everyone.
