The two sick birds will definitely have to be culled. I do not want to introduce them to the flock even if they were to get better. I am considering maybe sending them to the state for a necropsy to be certain of what the disease is. I really appreciate your support and advice.

Just an update for anyone who may be reading this or have a similar problem; I have treated the two chickens with a dose of Tylan 50 and will do so for 2 more days. They are still in strict isolation. When they are better I will be sending them to live with my mother in law who has no chickens so they aren't a threat to others. they should be able to live out their days happily there. I just couldn't bring myself to kill the poor girls.

It has also been around 48 hours since bringing the new chickens home and no others have shown any symptoms of being sick. So I'm remaining hopeful that it hadn't spread.

You might want to get one or both tested for MG and coryza. I haven't treated those, but any disease can be complicated by a secondary infection. E. coli is one that complicates respiratory disease. A bad smell may not always be a diagnosis. A blood test is best, and contact your state vet or local extension agent about ELISA testing. Sorry that you may have gotten sick birds.

Does the bird have to be culled in order to test for it?

No, they don't have to be culled, since you can get a blood test done. I'm not familiar with all of the testing that is done, but I think the ELISA test is good. Of course if you should lose a sick bird, getting it tested with a necropsy by the state vet may be a better option. Those can be free in some states, such as California, while in others it can be fairly low, but as always, in ome states it is pricey. It may help to speak to the state vet's office by phone or email. I have heard that it was $80 for a necropsy in Ohio. There may be a price list on the dept. of agriculture web site.

First off I want to thank everyone for their kind and helpful replies, and to bear with me because I have more questions! :D So today was the third day of Tylan 50 for the two original sick chickens. I just did not have it in me to cull them. When I went to give them the injections they looked completely back to normal; no sneezing, no discharge from the nose and no smell to them at all. I wanted to have nasal swabs done and was going to call today but now there is no discharge to swab! So I am at a loss at what to do. None of my other chickens are sick, I have been checking them daily for symptoms. How likely is it that this wasn't coryza??? The only symptoms they ever had were occasional sneezing and slightly runny noses that smelled bad. No swelling or anything that I have read about. Also, one of the injection sites for the Tylan is swollen (I have been injecting in the breast area). Is this normal?

I would continue the Tylan, but give it orally. It sounds more like MG now. Coryza is supposed to be very nasty with thick nasal and sticky eye discharge. Testing them now after antibiotics might not give accurate results.Here are some good article to read:

Here is some info from University of FL Extension Services:

 

Mycoplasma gallisepticum

Synonyms: MG, chronic respiratory disease (CRD), infectious sinusitis, mycoplasmosis

Species affected: chickens, turkeys, pigeons, ducks, peafowl, and passerine birds.

Clinical signs: Clinical symptoms vary slightly between species. Infected adult chickens may show no outward signs if infection is uncomplicated. However, sticky, serous exudate from nostrils, foamy exudate in eyes, and swollen sinuses can occur, especially in broilers. The air sacs may become infected. Infected birds can develop respiratory rales and sneeze. Affected birds are often stunted and unthrifty (see Table 1).

There are two forms of this disease in the turkey. With the "upper form" the birds have watery eyes and nostrils, the infraorbitals (just below the eye) become swollen, and the exudate becomes caseous and firm. The birds have respiratory rales and show unthriftiness.

With the "lower form", infected turkeys develop airsacculitis. As with chickens, birds can show no outward signs if the infection is uncomplicated. Thus, the condition may go unnoticed until the birds are slaughtered and the typical legions are seen. Birds with airsacculitis are condemned.

MG in chicken embryos can cause dwarfing, airsacculitis, and death.

Transmission: MG can be spread to offspring through the egg. Most commercial breeding flocks, however, are MG-free. Introduction of infected replacement birds can introduce the disease to MG-negative flocks. MG can also be spread by using MG-contaminated equipment.

Treatment: Outbreaks of MG can be controlled with the use of antibiotics. Erythromycin, tylosin, spectinomycin, and lincomycin all exhibit anti-mycoplasma activity and have given good results. Administration of most of these antibiotics can be by feed, water or injection. These are effective in reducing clinical disease. However, birds remain carriers for life.

Prevention: Eradication is the best control of mycoplasma disease. The National Poultry Improvement Plan monitors all participating chicken and turkey breeder flocks.

 

Infectious Coryza

Synonyms: roup, cold, coryza

Species affected: chickens, pheasants, and guinea fowl. Common in game chicken flocks.

Clinical signs: Swelling around the face, foul smelling, thick, sticky discharge from the nostrils and eyes, labored breathing, and rales (rattles—an abnormal breathing sound) are common clinical signs. The eyelids are irritated and may stick together. The birds may have diarrhea and growing birds may become stunted (see Table 1).

Mortality from coryza is usually low, but infections can decrease egg production and increase the incidence and/or severity of other diseases. Mortality can be as high as 50 percent, but is usually no more than 20 percent. The clinical disease can last from a few days to 2–3 months, depending on the virulence of the pathogen and the existence of other infections such as mycoplasmosis.

Transmission: Coryza is primarily transmitted by direct bird-to-bird contact. This can be from infected birds brought into the flock as well as from birds which recover from the disease which remain carriers of the organism and may shed intermittently throughout their lives. Birds risk exposure at poultry shows, bird swaps, and live-bird sales. Inapparent infected adult birds added into a flock are a common source for outbreaks. Within a flock, inhalation of airborne respiratory droplets, and contamination of feed and/or water are common modes of spread.

Treatment: Water soluble antibiotics or antibacterials can be used. Sulfadimethoxine (Albon®, Di-Methox™) is the preferred treatment. If it is not available, or not effective, sulfamethazine (Sulfa-Max®, SulfaSure™), erythromycin (gallimycin®), or tetracycline (Aureomycin®) can be used as alternative treatments. Sulfa drugs are not FDA approved for pullets older than 14 weeks of age or for commercial layer hens. While antibiotics can be effective in reducing clinical disease, they do not eliminate carrier birds.

Prevention: Good management and sanitation are the best ways to avoid infectious coryza. Most outbreaks occur as a result of mixing flocks. All replacement birds on "coryza-endemic" farms should be vaccinated. The vaccine (Coryza-Vac) is administered subcutaneously (under the skin) on the back of the neck. Each chicken should be vaccinated four times, starting at 5 weeks of age with at least 4 weeks between injections. Vaccinate again at 10 months of age and twice yearly thereafter.

Thank you so much for the information! I feel like all I have done the past three days is read lol. The woman I bought them from has agreed to take the birds back so I don't have to worry about that anymore. I suppose I will diligently watch the rest of my flock for symptoms. How long do i need to watch my flock for symptoms?

They can be carriers from just being exposed, and may not show symptoms. If you are very lucky, they may not have been exposed. As you will read in the links, they can show symptoms of MG within 3-10 days of exposure. Coryza may take only 2-3 days. Both organisms will only live in the environment for 2-3 days. I hope that sending them back solves the problem.
