This morning I saw my Black Giant, Beatrice, sneeze!! This afternoon she is also coughing!! And her breathing sounds like a little lawn mower or something!! What could be wrong??? Could she just have a cold? All the other chickens seem fine. She also seems fine (other than the respiratory problem), as she's not lethargic and in fact has been out free-ranging most of the day. I am really worried that this is the beginning of something bad!!
