I don't think they were the best videos because she definitely sounds different than normal. That said, I did just check on her and maybe the bread worked because she didn't seem to be wheezing so much. Think she's okay to be with her fellow chickens then? Thanks!
I noticed one of my light brahmas wheezing this morning so I immediately separated her and gave her a piece of bread soaked in olive oil. I haven't noticed it working yet. Any other suggestions? Here are a couple of videos to show you what the wheezing is like. She wasn't happy in the cage...
