So yesterday I noticed my 2 year old buff orpington hen showing some strange neurological symptoms. She was twisting her head around as if confused maybe and if she put her head back to far she would fall back on her rear end. Looking up videos of newcastle disease it seemed to be exactly what she was doing so I removed her from the coop and have her in a box in the garage to monitor her. I haven't noticed the head tilting and strange movements since last night but she is having diarrhea. Another thing worth noting is that she was drinking A LOT of water but not any abnormal thirst today. I really want to put her back in the coop because shes very stressed in the box but I don't want her passing anything to my other birds (if she hasn't already). Any thoughts or suggestions would be greatly appreciated. Thank you.
