There is a chicken at a place I ride and the person who owns that place just called me and said one of the chickens sounds sick! He doesn't have a computer so he wanted me to look into it... The chicken has making a noise kinda like she is saying eeeeeeee all day!! The sound of the e is like the first e in egg. This is a hen that is maybe 3 years old and has notlaid an egg all fall neither has the other hens... Help!
