Cinnamon is an ex-battery hen who weighs approx 1.5k I have had her since May 2015, and she is usually the brightest, greediest little girl. I noticed last night that she was sitting alone and disinterested in her surroundings, however she took herself off to bed as usual. She has layers pellets and fresh water freely available all day, with afternoon treats such as chicken treat mix, tomatoes, sultanas, lettuce, cucumber. with the occasional addition of porridge or Probiotic Yoghurt, and a handful of corn before bed on cold nights. This morning I found her in a nestbox looking sleepy, she came out when I called her, but was moving very slowly, and passed some green watery diarrhea. I offered her some food and water but she was not interested. I have checked her for parasites, joint swellings and any signs of egg peritonitis and found no problems. There is no eye or nostril discharge. She is currently sleeping in the quiet with food and water available. Her crop is empty, they were de-wormed in March and our vet did a parasite and Coccidiosis test which came back clear. Her tail is drooping and she has taken a couple of pecks at her food this morning but nothing significant. Can anyone help please?
