Diane, People cannot catch canker aka T gallinae aka trichomoniasis from birds - it is a bird specific protozoa, and not a zoonose. Have you seen T gallinae under a microscope? I have. Sideways they resemble pack man. Full view look like a pear with tails. It's easy to prep a slide with a mucus or solid caseous specimen, bottled water, and a decent microscope. Canker has a short life span out of the bird's body and usually are spread by wild birds drinking out of water dishes and a chicken drinking out of the same dish within a relatively short time.
I did years of research after buying chickens I knew had canker and watched the breeder pull chunks of it out of a rooster's throat. Quarantine, treatment/medication allowed me to breed from these beyond gorgeous birds. This situation has also resulted in my doing years of research and testing new chickens that I buy. Canker is more prevalent than people realize in the fancy and wild birds. Poultry can live with some lesser virulent strains if they are not stressed. Extreme weather temperatures and other stresses can impair immunity and allow these lesser strains over come a bird's immune system. Virulent strains kill within a short time, and the in
between of course cause disease/roup. What I do not understand is someone not taking immediate intervention for sick birds/poultry/livestock/pets. Birds are especially vulnerable as you pointed out due to their many air sacks and their hollow bones. Protozoa, viruses, bacteria, and mycoplasmas hide easily in congestion (no blood supply to deliver meds in congestion) and in their hollow bones. Mycoplasmas not only do the same but can hide in cell parts too.

I strongly suggest you look into pigeons. They are VERY prone to this canker, it's an ongoing battle, and there are a lot of treatments for them, including vaccines. Join a pigeon list and ask for help. Look for info on the net.
By the way, to tell the truth, I think you should kill the chickens, dispose of them, thoroughly clean their living area and start over. You can get sick yourself from this canker. It's a growth like a cancer, and it's catching. Pigeons, and chickens, like other birds, don't have the same lungs you do. They have air sacs all over their body and in their wings, the harder they fly, the more air they get. So they can get this canker all over inside their bodies, not just in the mouth and throat. And the spores are in their droppings. People can get it when they clean the coop, especially from dry droppings dust. Pigeon people wear a mask to do cleaning, and even then lung problems are well known and very common.
I'm sure this is not what you want to hear, but it's the truth. Sometimes you just have to make a break and start over.
With best wishes and sympathy,
Diane S.

oh yes I know... I am going to figure out w/ twin state what they think I should try next, the 4 in 1 or perhaps the med suggested by the other group member (Marlene?).
Thank you for your time!!
