I couldn't give Marshmallow a bath yesterday, I had a very bad migraine and was laid up all day. Anyways, I could tell today that she was weak looking and not doing good. So she got another bath and just as I was afraid would happen, the urates crusted over and clogged her vent. So I tried to work oil into it, and in her vent, to get all the stuff off. Poor thing was trying to help me, she kept making grunting noises and pushing. Then all of a sudden the gross plug came out and she pooped a giant poop! Sorry to be graphic but I have never been so happy to see a chicken poop! Then she kept pushing and grunting. My son was laughing at me cheering her on! Out leaked more urates but she was pushing poop out too. She stayed in the bath, with me massaging oil on her, for over 45 minutes! Then, I cleaned her up, rubbed more oil and vaseline on her to try and prevent more crusting on her. Used a blow dryer on low to dry her as best I could, and put her back in the coop. Then she wouldn't stand. Refused to support herself completely. I hope it's just from relaxing in the bath but I don't know. I did the best I could. We will see what tomorrow brings, hopefully it brings a Marshmallow that is stronger because she has eaten and drank water. Edited to add that the oil I used was vegetable oil, seemed to work good
