I just got back my girls last week, (they were on a organic farm for the winter, while I was in sunny fla) They are very healthy looking and seem to be very peaceful and happy. 3 days ago it was very cold and one of the roadys was acting sick, closing her eyes, stumbling a little, I put in a light to warm her, today she is very listless, trying to keep her head up and her breathing is a bit rhaspy. Does she have a cold? I have her isolated with heat. what does one do for a hen with a cold? I rescued these girls last summer, 4 rhode island reds and 3 aroconas, and am attached to them. Looking for some sound advice. Thanks, northern michigan girl.
