One of my 4 year-old Rhode Island Reds is sick! Her comb is droopy and she's lackadaisical and low-energy. Yesterday she was separating herself from the other hens as well (we only have four hens, total). Yesterday afternoon, my husband picked her up and what looked like water just poured out from her beak. We used an eyedropper to give her some olive oil and also gave her a little bread dipped in olive oil. She seemed to feel better after that, and ate some blueberries and grapes. We also put 1 Tbsp apple cider vinegar in a gallon of water in a plastic waterer for all the hens to drink from. This morning, she was in a nesting box and we think she laid an egg, but I'm not sure if it was hers or not. Her crop was swollen and my husband picked her up again and this time brown liquid came out. We don't have a chicken vet anywhere nearby that I know of and there's no way we're doing surgery on her. Should I continue with the olive oil or are there any other things we can try? I also read about boiling 10 garlic cloves, letting the water cool to room temperature, then giving her some of the water by eyedropper, but is that a good option? Any help is appreciated!
