I have a year old EE hen that has stopped eating, and drinking. I have tried feeding her all of her favorites today but she won't touch them. She is extremely under weight compared with the rest of the girls. When she breaths you can here rattling. Her eyes, and nose are clear. No discharge. Her comb is normal color. She is very lethargic. A little over a month ago she had cut her foot, and it turned into bumble foot. I treated it, and she recovered. I don't think it is related to that. The rattling concerns me. She isn't breathing with her mouth open, or gasping for air. It's just when she breaths it rattles. I think it might be too late for her, but if there is something I can do I will try. I APPLIED INVERMECTIN YESTERDAY AFTERNOON. IF SHE DOES HAVE GAPEWORM WHEN WILL WE SEE IMPROVEMENT? SHE IS STILL WITH US, BUT IT IS TOUCH AND GO. SHE IS VERY GURGLY THIS AM, AND HER COMB IS TURNING DARK RED. THERE IS NO DISCHARGE, AND EYES ARE STILL CLEAR. SHE STILL HASN'T EATEN. HOWEVER, SHE IS POOPING NORMAL POOPS. SHE WAS SCRATCHING AT HER EARS EARLIER. DOES THAT MEAN ANYTHING?
