Just checked the hens and Murial who has been on and off colour for a couple of days, not unusual for her but she is now sneezing and her eyes are watery. She is eating, pooing and drinking fine but looks more sorry for herself than usual. Will take to the vets tomorrow, but should I separate? and if so I can put her in a cat carrier but bit stuck as to where to leave her overnight? kitchen very warm, outside barn cold. Is there anything I could give her? If she has an infection I have to assume the others would already have it?
