Coryza Help!

[SandS Kluckers]

Help!! We culled our entire backyard flock after discovering they had coryza and hatched some of our beloved's eggs. Our chicks are a few weeks old and today I notice one weezing and think I smelled that nasty familar smell. We used nothing from our other chickens, have not been to the old coop or even that part of the yard.
I fugure that there ar two possiblities:
The eggs had it on them and gave it to the chicks when thay hatched?
OR
Is it possible that our border collie who loved and herded our chickens and is very attentive to the chicks is a carrier?

If someone has a clue please help we have more chicks to hatch and 20 new pullets aswell.

Thanks for the link, I feel that I've read everything the internet has to offer but still don't know why they seem to be sick.

Coryza cannot be passed through eggs as you know. It has a one to three day incubation period. Coryza can be passed directly from chicken to chicken, or by nasal droplets sneezed or slung into the air or passed from one bird to another via feeders and waterers. Your dog cant pass it to birds. Alot of times coryza and MG infect the flock at the same time, they kinda go hand in hand. MG can be passed through eggs, on clothing, hands, shoes etc...
I recommend that you get a necropsy performed or a bloodwork to confirm what you're dealing with. You can contact your local extension office for info how to go about getting a bird or chick tested.

Welcome to BYC! Did a vet confirm Coryza?

No, a vet did not but the putrid smell and all of the symptoms match. Of our eleven chicks only one is wheezy and sounds congested but is eating and drinking well. We have 48 chicks hatching friday and want to figure this out before then if possible. DO you think a vet is the only way to find out whats wrong and if so won't I infect the vets office if I bring it in?
We moved from Oregon a year ago and never had any problems.
We moved to Shenandoah Valley, Virgina meat chicken raising.
We got some chickens off craigslist that got sick and got our chickens sick. We think he must have been charged with killing them but sold them instead.
We just raise chickens for fun and eggs this is heart breaking.
Thanks for any advice or help

You could try something like Baytril. It's banned for use in poultry, so read up on that before you decide to buy it. http://www.cidrap.umn.edu/news-perspective/2005/07/fda-ban-enrofloxacin-use-poultry

You can buy Baytril here:

Treatment for coryza is sulmet in combination with baytril or tylan. The baytril or tylan will treat MG, sulfa meds will treat coryza. Sulmet 12.5% liquid dosage info is on the bottle.

I think Baytril also treats Coryza alone.

Edited to add:

fluoroquinolones = Baytril

Preventive medication may be combined with a vaccination program if started pullets are to be reared or housed on infected premises.

Infectious Coryza in laying Hens

Infectious Coryza is a tenacious respiratory disease which tends to become chronic in laying hens that were infected during rearing. Antimicrobial therapy of layer replacement flocks affected by the disease, e.g., before protection by immunisation can be established, is appropriate in order to safeguard future respiratory health.
In a clinical study (Will B., 1986), drinking water medication with Baytril

10% oral solution was shown to be very efficacious against Infectious Coryza with rapid reduction of morbidity and full microbiological clearancefrom the infectious agent, Haemophilus paragallinarum, at the end of medication.

Activity and Susceptibility Data[edit]

Enrofloxacin is a synthetic antibacterial agent from the class of the fluoroquinolone carboxylic acid derivatives. It has antibacterial activity against a broad spectrum of Gram-negative and Gram-positive bacteria. Its mechanism of action is not thoroughly understood, but it is believed to act by inhibiting bacterial DNA gyrase (a type-II topoisomerase), thereby preventing DNA supercoiling and DNA synthesis. It is effective against:

• Pseudomonas aeruginosa
• Klebsiella
• Escherichia coli
• Enterobacter
• Campylobacter
• Shigella
• Salmonella
• Aeromonas
• Haemophilus
• Proteus
• Yersinia
• Serratia
• Vibrio
• Brucella
• Chlamydia trachomatis
• Staphylococcus (including penicillinase-producing and methicillin-resistant strains)
• Mycoplasma
