We have a Red Star hen just under a year old. This is the second day she has been rasping and occasionallly sneezing. She does this a couple of times a day, not all the time. She is laying, eating, drinking, and acting normal. No other symptoms. No others in the flock are showing any symptoms but I have been finding very thin shelled, rough eggs; I think they are from another hen, not her,I know where she lays. and I also think the thin shelled rough eggs are from just one hen. We are going to catch her and examine her in a bit, she is still ranging with the flock right now. If this is Newcastle/s would others be showing symptoms by now.? Please has anyone had any experience and/ or positive outcome from this disease? I am very worried.
