Does anyone know the symptoms of congestive heart failure in chickens? I've got a 5 and 1/2 year old hen whose feathers are ruffled. Her comb is pale (although it doesn't seem as pale tonight as it has been). She makes a small honking noise when she breathes sometimes. She has developed a baseball-sized ball behind her legs that is soft, not hard. She eats and drinks and walks around the house, pecking at the floor when we let her out of the infirmary cage she is in. She is not in the penguin position. She's been like this for about three weeks. We've already been through a week of Terramycin. I don't think she is egg-bound or internally laying, but what do I know?? For some reason, I think it may be congestive heart failure. If that is the case, is there ANYTHING I can do for her?? Thanks for any help you can give me.
