Hi, Need some help. My hen, a blue Andalusian who is about 5 years old, was fine this morning but later on I checked in the coop to see if everyone was ok and she was standing by the water dish and wheezing. The noises she is emitting sound exactly like the hen in this you tube video: I should note that she was treated with topical (on the skin) ivermectin a few days ago. I had one hen whom I treated yesterday with ivermectin dead this morning in the coop. I have no idea if the two things are related or not, but I did check with signs of ivermectin poisoning and none of them were wheezing. After giving my hen some water and olive oil, and also feeling around her throat for blockages (there were none) and also looked down her throat for blockages (I couldn't see any), I also smelled her breath to see if there was any odor, there is not. Her eyes are clear and bright... nothing looks like it is sinus related. None of the other hens are doing this or showing any signs of stress/illness.. except the one that died suddenly overnight. My only guess would be she got mated and when the rooster hopped on her she might have breathed in some small particles of pine chips from the floor? When I put her back in the coop after observation, she seemed ok- she seemed interested in getting back to normal. She was still wheezing/sneezing/ and coughing at the time. I will check back occasionally. She does seem like she is struggling for breath a bit. I'm at a loss as to what to do. At this point, I think its probably some sort of lodged particle in her esophagus. I tried tilting her upside down to dislodge anything or make her throw up if she needed, but again, nothing. Has anyone else had this before? She is sounding EXACTLY like the hen in the video link above.
