One of my cot hens is ill. She is puffed up and a clear discharge is coming from her eyes and nostrils. She holds her head up with her eyes closed and swallows. I picked her up and she was really light and then a brown liquid poured out of her mouth. It had a strong unbearable stench. I have never seen an illness like this and she just got ill out of the blue. I have her separated the other quail are not showing any symptoms. Should I put sulmet or duramycin in her water. I believe she does drink water as I found her standing next to the water dish. What could she have? Has anyone experienced a quail with these symptoms?
