Today when I let my hens out to play, one of our Buckeye hens remained in the run. She was just standing there with her eyes half closing. I went in the house and changed into my grubbies figuring that I would have to do some inspection which may mean that I would be in contact with a poopy butt. I picked the hen up and tucked her under my arm like a football. I wanted to inspect her bottom so I had her with her head facing behind me. I tipped her slightly to check her for poopy butt, her bottom was fine. However, as I was inspecting her bottom, I felt a warm sensation on the side of the leg below the hen. When I set the hen down and looked at myself, the entire side of my jeans, in the thigh area, was soaking wet. Apparently, my hen's crop was distended with fluid or water. I felt her crop, and it was very spongy.. I am thinking that she may have sour crop? After I put her down, she walked very slowly to the warm south side of our house to be with the other hens. I have read on other threads to treat this with ACV in water, good quality yogurt mixed with chick feed? I have a very good quality probiotic capsule that I take myself. Would it be okay to mix that with a little warm water and acv with the chicken feed? Or do I not give feed for a period of time and only give acv water with probiotics, wait to see attitude improvement and then give feed mixed with acv and probiotics? Also, is it imperative that she be separated from the others?
