I've been reading lots of posts, but not finding much that nails down my issue. About 4 days ago, I came home to a hen with wheezing sounds & seemed to be struggling breathing. No other issues such as eye or nasal discharge. She was scratching around & acting completely normal. About 4 hours later after researching, I gave her some bread soaked in olive oil as several posts suggested. The wheezing/struggling to breathe pretty much stopped after that. I listened several times during the night I didn't hear any issues. The past few days, she has sounded really hoarse when talking to me & breathing sometimes sounds a little tight. She has been continuing to lay eggs daily & act completely normal. Still no facial discharge or swelling. Maybe/maybe not related..the tips of her wing feathers have seemed to curl out some, looking ruffled. Noticed this starting several weeks ago and today they seemed to be worse (weather has turned colder). The reason this stands out is we have another hen the same breed whose feathers lay down smoothly. We have 4 hens and these issues are only in the one hen. They are free range. We use pine shavings in the hen house. If anyone has any ideas or experiences to share, I love to hear from you. Thanks!
