This morning my Barred Rock was perfectly fine and a few hours ago I noticed that she was breathing funny. She kind was opening her mouth and gasping sort of but with out the noise really. I have a video that I took with my phone but I can't it to load. Does anyone have any ideas what is wrong with her. I added her to my flock this past Tuesday along with a australorp rooster and a few days before that I had added a red sex link to our two girl that I had since they were chicks. They are all about four months old.
