Should I give this to the entire flock?

I have watch all the YouTube videos with chickens infested with Gape worms, and my hen doesn't behave like that. She has a very good appetite, she is lively and loud, good color on her face, and the only symptom of a sickness is the sneezing. I have been using VetRx every evening on her, and she seems to sneeze less, however this morning I noticed a yellow discharge from her nostrils, and that’s why I believe is sinus infection and not respiratory infection.
She has been with the rest of the flock from the beginning, and none of the other chickens show any signs of sickness or sneezing.
From what I'm reading on BYC, I understand that there is also the possibility that she has allergies, and in that case the antibiotic will be unnecessary but will not harm, and the organic de-wormer is something that I was looking to get anyway since I never de-wormed my chickens.

Normally she doesn't stretch her neck when she sneezes like she did in this video.

Anyone?

I hope someone has something for you - I haven't had to deal with any type of sinus or respritory issues. Just bugs ....

Could be CRD, I would separate her from the others. Some will tell you to let it runs it's course without antibiotics, so I would say that is a personal choice, the course will be about 6-10 days. But, it is contagious so you need to separate her until she has recovered.

What is CRD?

Chronic Respiratory Disease. You might see nasal discharge and sneezing. Check out the MG forum. It has alot of good information about MG/CRD.

Chronic Respiratory Disease/ Mycoplasmosis =CRD. Yellowish snotty discharge can be a symptom of that, not just a sinus infection. Unless you have a test to determine what she has, I can't recommend anything other than removing her from the flock permanently. If you do choose to treat her, just know that CRD makes a bird a carrier so this will keep coming up if she does have CRD/MG. And CRD can be passed down through the egg to a future chick as well.

As with humans, antibiotics do nothing for a virus, so if it's viral, Duramycin won't fix it.

Most folks use a 2-3 week egg withdrawal after antibiotic dosing, if you choose to go that route.

The sinuses are part of the respiratory system so an infection there is sort-of the same thing. With the nasal drainage and sneezing I would really not start thinking about gape worm. She very likely has a respiratory infection and it is contagious. It is unlikely that she just has allergies. I would isolate her as soon as possible. Also, if chickens have worms DE will not get rid of them. DE is really not going kill worms, might help prevent. If you really want to use DE, I wouldn't worry about adding that with antibiotics if that is what you want to do.

The birds may have already been carriers of the disease and just were stressed enough that it showed itself. Good luck with whatever you decide to do.
