Help-- I can't stop a Coryza outbreak!!

[AndyC]

I introduced 2 new birds to my flock and they had coryza, I didn't know this and put them in with my others. I have since culled those two out of the coop. My birds have been on Sulmet for a week and some seem to not be affected at all. But another one started wheezing and sneezing yesterday. Will more Sulmet take care of this problem or will it keep spreading? How long does it take to cure? Any advice would be helpful I don;t want to lose my whole flock!

THat is why a quarantine period of at least 30 days is always the smart thing to do. Coryza is not curable and the chickens will be carriers for life. ANY chicken that comes near them will get it. THE only way to cure coryza is to cull every bird that has come in contact with sick ones and disinfect EVERYTHING and start over.

I believe "purple Chicken" Had this problem and found out that he DID NOT have to cull ALL of his flock.

It does get tricky though. There WILL BE a carrier if one does not cull the sick birds. If left alone a bird will get over the illness (or die) and then become a "carrier" for life.

Guinea fowl seem to have a strong resistance to this disease and the breeding stock such as the white rocks, the leghorns, the australorps, the NJ giants, the orpintons, the cochins, the wild games and games in general seem to take it in stride or die within a week.

Coryza is a very nasty disease and I would not wish it on any one here.

I am so sorry this has happened, but you REALLY need to find out if it is IN FACT Coryza.

MG or Chronic Respiratory Disease (CRD/MG) has a very similiar outward appearance.

CRD is not as devastating as Coryza and birds that become immune live a long life, but are carriers as well.

Please see my BYC pages as I do have information on a good deal of diseases that affect poultry.

Read this from the Merck Vet. Manual on-line. It is very informative about Coryza and yes it is treatable.

A vet can can do bloodwork to make sure that Corzya is what you are dealing with. Most of the resp. diseases in chicken have the same symptoms and it takes testing to find which your birds have.

Is there any other diseases this could be I see no other signs of Coryza just a coughing and chest rumbling like there is fluid in there. I really don;t want to destroy my whole flock

 

[nnbreeder]

There are many that it could be. Do you have anything other then Sulmet on hand?

 

[AndyC]

No I just have the sulmet, because the person I got the sick birds from said to use this. I also just read that you are not supposed to use sulmet in layers. does this mean ever, or just not to eat the eggs when they are on the medication?

 

[nnbreeder]

The main drugs that I keep on hand for critter treatment is Pen-G injectable, LS-50 and LA-200 injectable. Tylan-50 and Tylan-200 injectable are both very good to have on hand and can be bought at Tractor Supply. The Tylan works well for most resp. diseases.

 

[nnbreeder]

If a drug has not been tested for residue in eggs then it will say not to use in layers as does the Wazine-17 wormer. I follow the slaughter withdrawl times for broilers on tossing eggs.

This really sucks!! I am not sure if it is Coryza or not. If it is not then I don't want to eliminate all of them. my other chickens that went on the sulmet immediately show no signs of illness but a newer one that came after the sulmet stopped got sick. it is very frustrating.
