Good afternoon! Last Tuesday my 2.5 yo Speckled Sussex hen started acting odd (was perched outside after dark usually goes into the hen house with the 2 others). I did not think too much of it. Wednesday appeared slow/sluggish not eating much. She is normally my most energetic sweet spirited hen so for her this is very unusual. Thursday a.m she was laying in run with yellow white (appeared to be yolk) coming from vent. Thursday afternoon did a cloaca exam and gave her a warm soak. No impacted egg found. She seemed perkier than days before. Thought she was on the mend from whatever is going on Friday appeared well. Mostly spunky but not 100%, eating drinking being social. Saturday a.m found her in the nest box for over an hour, beak open, trying to lay. No egg produced. Did another cloaca exam and found nothing. Abdomen area appeared swollen to me however I do not really have a baseline to go from Sunday appeared well however took her to the vet for an exam and xrays. Vet noted that she was skinny and her crop was full and wanted to wait until the images came back to determine the rest. Massaged crop and it emptied Monday appeared mostly well but still not her 100% self. Eating and drinking. Being social. Monday night received the radiography report. Tuesday same as Monday. Based on the xray report I am looking for recommendation on how to proceed forward. I do realize from what I have read that egg yolk peritonitis is eventually fatal. However it is hard to be convinced what is going on because she mostly appears okay. I do realize that she has not laid and egg since Tuesday at least from what I can tell. The vet is not well versed in chicken health and has recommend another physician. He also informed me that they are legally not allowed to give antibiotics. I sincerely do not want this sweet girl to suffer. I want to do what is best for her. Any advice or suggestions would be more than welcomed. Thank you for taking the time to read this! I am attaching her radiology report and her most recent stool from today.
