I noticed a couple days ago my guinea fowl hen seemed to be sneezing. I don't know if she is sick or if it is just another guinea sound. Other than that she does not act sick. When she makes this noise it just happens she doesn't even shake her head. I had a sick rooster in there a week ago but I culled him. Could she had got it from him? They are in with the chickens. None of the chickens are sick so what is going on?
