Here's the background: 1) What type of bird , age and weight Gold Laced Wyandotte hen, one year old, seems normal weight. 2) What is the behavior, exactly. Sort of a coughing or wheezing noise. About a week ago, hubby noticed her making a coughing noise that was almost a cawing, but then she stopped again after a few hours. She didn't seem to display any other symptoms at the time. Now she has a constant sort of rattle or wheeze when she breathes, and seems like a small amount of discharge from the nares. No bad smell. 4) Are other birds exhibiting the same symptoms? Nope, not a one. All the other birds seem to be acting normally, at least for now. 5) Is there any bleeding, injury, broken bones or other sign of trauma. Nope. 6) What happened, if anything that you know of, that may have caused the situation. No clue. 7) What has the bird been eating and drinking, if at all. Layer pellets, and we pasture the girls so grass and worms. Clean water daily. 8) How does the poop look? Normal? Bloody? Runny? etc. Haven't checked her poop individually, I will have to watch her until she poos. 9) What has been the treatment you have administered so far? None yet. 12) Describe the housing/bedding in use Enclosed coop with pine shaving bedding, I change it whenever it looks poopy. Ventilation is fine, big open window on the front. Enclosed run (hardware cloth) with dirt floor, and pastured outdoors regularly in a fenced yard we move around every week or so. I was reading some other threads on chickens coughing. I am concerned it's something like infectious bronchitis, but not sure how it could be since none of the other hens are showing symptoms. So I wondered if it could be gape worm. We live in a rural area so plenty of wild birds, especially wild turkeys in the area. And the birds do eat worms, they adore them whenever they can scratch them up. But I don't want to assume anything. Is there a way to tell if it is gape worm? Thanks for any help!
