I have 15 hens and one rooster. The other day I found one hen dead on the roost. She showed no signs of illness and I checked her over and there were no wounds. So I assumed it was just one of those things. But I went to tend to my flock this morning and now I have one that is acting less than spunky. I went over to her and noticed her breathing sounded gargled and she looks like she's gasping. I don't know if there is some sort of disease going through my flock!! Any suggestions???
