I've done an extensive search but didn't find anything that really fit. She's acting absolutely fine, laid an egg today, droppings are normal. Her breathing is noisy, that's it. No nasal discharge, no coughing or sneezing. To answer the suggested questions: 1) What type of bird , age and weight. easter egger, 14 months old, approx. 5 lbs. 2) What is the behavior, exactly. noisy breathing 3) How long has the bird been exhibiting symptoms? For about 4 hours 4) Are other birds exhibiting the same symptoms? No 5) Is there any bleeding, injury, broken bones or other sign of trauma. No 6) What happened, if anything that you know of, that may have caused the situation. In the middle of the night last night we had our first significant rainfall since May. The birds were in their dry coop of course, but it does have large windows. It's very damp today. 7) What has the bird been eating and drinking, if at all. She's eating well - flockraiser, seven grain scratch, a tiny bit of cheese and banana (the cheese and banana after the symptom started), drinking both city water and well water. 8) How does the poop look? Normal? Bloody? Runny? etc. Normal 9) What has been the treatment you have administered so far? None 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? At home treatment only 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use chickens are in a 12 x 14 coop (20 chickens, various ages), with plenty of ventilation, bedding is pine shavings. They free range all day. I only have two antibiotics on hand right now, Pen G Inj. and tetracycline.
