1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.) She's a mixed breed. Other members suggested a polish/production breed cross. She's about two years old. 2) What is the behavior, exactly. She has a cloudy snotty nose. 3) How long has the bird been exhibiting symptoms? I just noticed today, but the last time I took a close check on her was a few days ago. 4) Are other birds exhibiting the same symptoms? Not that I've seen. 5) Is there any bleeding, injury, broken bones or other sign of trauma. No. A few months ago she had a bad injury to her side, but it's since scarred over. 6) What happened, if anything that you know of, that may have caused the situation. WE've been having temperatures -9 or colder without wind chill. With wind chill, worse. 7) What has the bird been eating and drinking, if at all. Yes, Layer pellets and whatever water isn't frozen at the time. Just plain tap water. 8) How does the poop look? Normal? Bloody? Runny? etc. I can't tell which hen poops what. 9) What has been the treatment you have administered so far? Nothing yet, just noticed it. 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? I can't afford a vet, nor do I have one that would be willing or able to care for a chicken. 11) If you have a picture of the wound or condition, please post it. It may help. I'll take a picture within the hour. 12) Describe the housing/bedding in use 8x6 or so coop, whitewood shavings, deep litter method. Plyboard coop, wood floor. Hay in nests.
