My hen Opal is breathing very strangely. I have brought her inside. Currently have the vaporizer with oxine running. She was like this a couple of weeks ago. I had her in for a few days. Treated with tylan 50 injectable and the oxine. She was breathing normal and wanted out of cage so I returned her to the flock. Also gave her a dose of valbazen but have not yet given second dose. She is eating and drinking. Poop is good. She has not layed in quite awhile and her last few were soft shell. She is about 1 1/2 yrs old bo. She also had a bumblefoot which my husband and I performed surgery on. Poor girl has had her share of troubles lately! No one else is showing any breathing issues. Is it respiratory? I made a video but can't figure out how to add it to this post. I have several medications on hand but not sure which would be best for her. I have oxine, tylan, corid, duramycin, la200, sulfadimethoxine, denagard, not sure what else. Oh and I have baytril on the way. Also have safeguard and valbazen wormers. What would you suggest to help my poor Opal?
