I have a 1 1/2 year-old EE that has been honking/wheezing. This has been off and on for a couple months. At first I thought she might just have a sensitivity to any dust that she gets into. She has not behaved any differently. Has been consistently eating, drinking, and laying. At one point, I did worry her crop felt a bit hard (but has never had a nasty odor), so I helped her vomit as I hung her upside down to gently massage it. That seemed to help and she behaved normally after. Now she has once again begun to honk and wheeze, but has more labored breathing and neck stretching. Today she was less energetic and hung back from the rest of the flock for some of the day, but has not been completely lethargic. She has continued to lay and laid a beautiful, strong, blue egg just yesterday. I have applied Vet Rx to her nostrils because they sound a little stuffy. I have spent the day online and reading my Chicken Health Handbook, and I am still confused! The other 4 chickens in my flock have always been perfectly fine while this one has had these issues. I do have her isolated, but I cannot figure out if this is a crop infection or respiratory. This is the only one of my chickens that has had any real issues of this nature, so I am not sure whether to assume infection and put her on Tylan 50, or to try other homeopathic remedies for impacted crop. From all I have studied over the time I've had my flock, if it was respiratory the whole group would have gotten ill a long time ago but they have always been fine. She is the only one that seems to keep having recurring issues. Thanks for any advice.
