Ok. Ill give a short version of the history. I was interested in getting a variety of chicken breeds and breeding on small scale because i love chickens. I care for my chickens as best i can and spent a lot of time researching breeds, incubation, diet requirements and illnesses. I plan on showing poultry next year, and buy only from well known and respected nreeders in South Africa that sell exibition quality birds. I currently have 10 breeds ofd chickens. Some of the breeds I own we habe less than 12 in the country. Keep in mind that south agrica doesnt have the vatiety or the numbers that tou guys may have. Its very common for our birds to gey sick. My goal is to take these rare birds and vaccinate and cull selectively to get healthy stock. I vaccinate because when you show poultry they get ill. I realise vaccination doesnt treat illnesses. But i try to vaccinate to get a clean start in offspring. My birds get the following treatment: they get a quality feed together with fresh lucern daily. I give probiotics once a week. They gey garlic in their feed. The get vitamins in their water 5 days a week. Cages are sprayed two times a week with virukill. Cages are cleaned daily. The do freeramge when possible
under supervision we have predators around. Sick birds and new birds are kept seperate and medicated. All birds are vaccinated whem healthy. Babies are kept seperate and vaccinated. They also get cooked eggs onve a week. And a cooked lentil amd brown rice mixture twice a week. They also get organic minved game meat or fish onve a week. I deworm new birds and i dewor! Roitinely onve every three months. I also spray cages once a month for lice and mites. I also then put karba dust on the chickens. I dont allow visitors in my cages they are only allowed in the feced hallway to view chickens. I keep this hallway clean by using virukill and bleach daily. We dont have a vet that is willing to help witjh chickens. I can only give you the symptoms and the symptoms for the birds are not the same since i got different birds from different breeders. The reason for this is like i said i am trying to start up with different breeds and breed healthy stock. Ymptoms of sickness a: sussex en leghorn chicks had sneezing, nasal discharge amd twisting of the neck, these birds were culled. Symptoms of sickness 2: combs turining dark purple gaping for air and sneezing. These birds were culled. Symptoms of sickness 3: one eye swollen shut. Sneezing, shaking of the head. These birds were extreely rare and they were medicated. The symptoms are gone. Sickness 4: wheezy breathing and coughing. These are rare breeds and the were medicates. Sickness 5, orpingtons. Gaping for air and coughin.
HI there, I am really sorry to hear about the issues with your birds. Upper respiratory is one of the most common health ( and life threatening) issues with poultry. Chickens have a very small trachea (windpipe) which makes an upper respiratory more life threatening if not treated right away (if it is bacterial). Which brings me to my next point. Upper respiratories can be viral or bacterial. This is a list of some of the more common and how long the bacteria/virus can survive in the environment:
- Avian influenza – Viral Days to months
- Coryza Viral Hours to days
- Newcastle Disease Viral Days to months
- Mycoplasmosis Bacterial Hours to days
- Infectious Laryngotracheitis (Ilt, Laryngo) –Viral
- Infectious Bronchitis Viral
Even with your clean environment that you have made for your birds, viruses and bacteria can find their way in, some are airborne and can travel a good ways. They can also be transmitted by rodents and wild birds. It takes a whole country of participants to eradicate those diseases. I can't imagine what it is costing you to try to produce healthy birds.

Without knowing what you are treating I don't know that you will be able to get ahead of it. You can't successfully treat a viral infection with an antibiotic. Without proper diagnosis the question arises as to how long should you treat with antibiotics? And if the bird does get better should it be put back with the general population, as in some conditions even if they recover they will be carriers for life (Mycoplasmosis) . And not being able to acquire healthy vaccinated birds has already given you a huge disadvantage.
Are you able to bring in healthy vaccinated birds from another country? Is there anyone who can test your birds to see what all you may be dealing with? Again I am really sorry, it must be incredibly heartbreaking. I wish there was something we could do to help you.
