Well I'm finally back from town.

Infectous Coryza. A nasty disease that will rip through a flock overnight.

Here is what the Merck Vet manual says about the treatment for Coryza.

Control and Treatment:
Prevention is the only sound method of control. “All-in/all-out” farm programs with sound management and isolation methods are the best way to avoid the disease. Replacements should be raised on the same farm or obtained from clean flocks. If replacement pullets are to be placed on a farm that has a history of infectious coryza, bacterins are available to help prevent and control the disease. USDA-licensed bacterins are available, and bacterins also are produced within states for intrastate use. Bacterins also are produced in many other countries. Because serovars A, B, and C are not cross-protective, it is essential that bacterins contain the serovars present in the target population. Vaccination should be completed ~4 wk before infectious coryza usually breaks out on the individual farm. Antibodies detected by the hemagglutination-inhibition test after bacterin administration correlate with protective immunity. Controlled exposure to live organisms also has been used to immunize layers in endemic areas.
Because early treatment is important, water medication is recommended immediately until medicated feed is available. Erythromycin and oxytetracycline are usually beneficial. Several new-generation antibiotics (eg, fluoroquinolones, macrolides) are active against infectious coryza. Various sulfonamides, sulfonamide-trimethoprim, and other combinations have been successful but must not be used in layers. In more severe outbreaks, although treatment may result in improvement, the disease may recur when medication is discontinued.
Preventive medication may be combined with a vaccination program, if started pullets are to be reared or housed on infected premise


That is from this page.

From personal experiance I can tell you that against Coryza, Baytril, from the vet only, is the way to go. In a couple of days it will be knocked out of the flock.


Here is the jumping off point for the Mycoplasm illnesses. This page lists links for each seperate infection.

MG is the most likely thing that you will come across so I am pasting that page here.

And yes if they survive the disease in times of stress they might shed the disease without showing signs of illness. People that get their birds treated for Marek's disease also have birds that are potential carriers. And they can also be a danger to flocks nearby that are not immunized against it.

UPDATE: Sent 3 hens with symptoms in for necropsy wont know anything for 5 to 10 days. Extension office said they were pretty sure it was respiratory related (everyone on here was right in your ideas THANK YOU!

) I have been researching like crazy on this subject thank you for all the links of research, it's not looking good. It appears what I was treating as a cold last Spring may have been the same thing, but i had no swollen eyes and no deaths from it just some runny noses and wheezing that went away relatively easy. I have no other birds showing symptoms been treating all birds with injections of Tylan 200 1/2cc but they have been exposed which means they are still carriers with no cure possible. So now i'm stumped about how to disinfect my coops. My floors are dirt. I treated everything inside with disinfectant from my local co-op. The floors I pulled all shavings and shoveled out what seems a ton of dirt and then disinfected everything; brought in new dirt and shaving. Even sprayed wire mess, do you think it is safe to move my medicated birds in?

I hate to destroy all my birds but i'm thinking this is about the only sure way to get rid of it.
