Hello. Basically, I was gone for a week and a petsitter was watching the chickens. I came back today, and I noticed that my black silkie has been wheezing, or something. It rained a couple times two weeks ago, she wasn't doing it then. None of the other chickens are doing it, but she is. It sounds sort of like what this chicken is doing but softer. What does it mean when a chicken is making this sound? If she is sick, how can I cure her? There aren't any vets that treat chickens in my area. Please help!
