yesterday when my hens were outdoors, I noticed one that was hunkered down in the dirt, I thought she was sun bathing but then when I looked closely, it looked like she was having difficulty breathing. So I brought her into the coop and isolated her in a small cage and started the heat lamp. She is not touching food or water. Today she is basically in same position, but now is sleeping off and on and has a steady clear runny nose. Suggestions? Oh, it is about 1-1/2 years old and a Rhode Island Red. I live in the Maine so weather is somewhat cold and almost to the point where I will leave all my birds in the coop and open a window for fresh air. I checked her bum and she does not seem to be egg bound. **Update** The hen died this morning.
