Treating what seems to be a recurring respiratory illness - possibly environmental?

[Lyris]

I've long since accepted that I have what appears to be an eventually fatal respiratory illness within my flock. Sneezing, coughing, congested breathing... It's responsible for the deaths of four of my chickens and seems to be antibiotic resistant. A couple of my chickens ended up with another home (they're aware of the illness and my chickens are the only ones they have) I've kept in contact with them and it appears they've had much better luck than I have. Aside from some minor sneezing during times of stress, they haven't had a single problem. Mine never fully get rid of it and it just gets worse. I'm wondering if it's possible that there's something in my environment that's possibly making it worse.
My chickens sleep in an old wooden shed I've repurposed for them. The shed itself is big enough that I could lay down in it comfortably. It's as tall as my house and has actual windows. Despite the many different types of perches and roosts I've given them they all prefer to sleep on the built in bookshelves so I have mini perches on various shelves for them. is it possible the old wood could be making their issues worse? Maybe dust? Could I put something over the wood (straw, sand?) to help keep down dust or any illnesses? I can't make major renovations to it since 1) I'm incredibly poor right now and 2) It's actually a structural part of my carport.

I'm not sure if this should go into illnesses or coop design, so sorry if I get it wrong.

I'm sorry you're dealing with illness.

It's possible something in the environment is exacerbating the respiratory illness. Poor Ventilation, mold/mildew, excessive ammonia from droppings are a few irritants to consider.

You mention your coop does have windows, these may let in air, but does your coop also have ventilation up relatively high to allow ammonia, dust, etc., to escape - air flow.

If you have any wood inside the coop that is moldy or mildewed and there's not a lot of ventilation, it's possible that this can be a contributing factor.

If you have photos of your coop (inside and out) you wish to share, we may be able to offer some suggestions about how to remedy any seen issues.

I had a respiratory illness that was recurring. Eventually I took them to the university vet. I took the 3 sickest who kept getting it again although they never died, some would. He euthanised those 3 and I didn’t have a problem fr years after that.

Hate to say it sounds like Mycoplasma, but unfortunately there's about 5 other similar respiratory diseases, like Coccidiosis , it could be. Especially if it keeps coming back, that's very common with the Mycoplasma.

Do the sickest ones just have the symptoms you mentioned? Any rales, gaping/ opening their mouth, swelling around eyes or nose? Are they eating normally? How does there poo look?

I've previously had respiratory issues ( didn't end well) and usually my go to things are:

-Add oregano and red pepper flakes to food. Usually if they won't eat the layer pellets, I switch them to chick starter or layer crumbles and add Kalmbach Hen House Reserve on top, Sometimes mealworms and/ or black oil sunflower seeds.
Making oatmeal and adding in an egg or the mealworms/ sunflower seeds works too.
-Add Poultry Cell or the Duravet to water. ( the duravet smells very strong of oregano)
Apple Cider Vinegar works in a pinch too.
-Add a few drops of vet RX. (Helps if you can't find the Duravet or the vitamin/ electrolytes
- Treat with Corrid
- Treat for worms. ( Sometimes worms like gapeworm can cause respiratory issues)
- Increase food for Calcium, Protein, Vitamin B and Vitamin D

If you treat with Corrid first, then it goes away, would mean they had coccidiosis. They do get more lethargic though as far as symptoms . Mycoplasma comes and goes depending on stress and weather. Infectious Bronchitis, Laryngitis or Gapeworm affect the throat/ voice too.Easier to tell in roosters. Hard overall to tell what it could be without testing or a necropsy though. I've previously used a testing facility that had either blood or swab testing. They have kits in qty of 3, 10, or more. I was able to mail it in. I think they do have a combo test that tests 5 things which can be pricy or a pay per test if you only need a few done. I'll have to see what the website was.

Sometimes I found it's better to just
treat for several things at once. Especially if the first dose wasn't enough or the first dose was for treatment and then subsequent doses for maintenance. Or depending on flock size. My old flock was hard to separate 10 chickens when you got 60 and by the time you figure out what the illness is or when they finally show symptoms. Unfortunately they hide illness so well.
