Are some respiratory infections just NOT a big deal? Or are they all a threat to the flock?

Hi all -

Reposting this with a new title hoping to get a new kind of answer.

I'm looking for your experience with chickens with recurrent breathing problems. This is basically a question of to cull or not to cull.

We have a - likely older than 3 years - RIR, who came to us with her 2 longtime flockmates in September. She was well and possibly even laying a egg now and then. In early November we added 3 young Leghorns, all about 7 months old and they began laying within 6-8 weeks. They've all been healthy, but at that time we didn't know about quarentining and we merged the two groups within a few days. The leghorns have never shown any signs of illness.

About a month after the leghorns arrived, the RIR developed a snore and gurgling breath sounds. The morning after we first heard this, she was kind of isolating herself in the yard and even laboring to breath so we brought her in our house and quarantined her, with extra warmth. She slowly improved each day, though a week later was still rattly. At no time did she have swollen nostrils, discharge from eyes or nostrils, or change in appetite, droppings, or curiosity - aside from the breathing, she was still as perky as ever. After that first week, we were getting a little tired of the clean up job, and a little worried that this was now a forever condition - possibly a tumor, though she had no obvious masses. A local vet did a fecal smear and saw no suspicious organisms, but gave her panacur and doxycycline just to cover all the bases. He did this by phone consult and no physical exam (our choice to save $). During the course of treatment she got entirely well - but it wasn't clear that it was the meds that did the trick. Coincidentally, we came into a warm spell though we live in an area with true winters (a cold snap has nights around 0 F.) I kind of hardened her off again by having her in a little pen near the big chicken yard for a few days and then she rejoined her flock. So that was around December 20 that she went back out.

Now here we are at the beginning of Feb and she's having a recurrence, and... so is one of her original flockmates, an Auracana, also likely around 3 years old. I've brought them both back into quarantine. Again - no discharge, no change in energy, appetite, etc. And again, both are improving.

I see a lot about the various illnesses that are more obvious with other signs like discharge, but nothing about something that seems so mild. It would seem obvious that this is contagious, but perhaps it's more to do with age and my newbie lack of experience keeping the coop dry enough (using deep litter method, diatomaceous earth, removing large wet areas, good air flow, but what do I know...)

And of course, now there are 4 new hens to want to protect, also hand-me-downs, on deck as it were in a separate pen and I am running out of ways to keep everyone separate.

Any thoughts? I feel like our choices are: 1. return them to the flock and hope for the best or that at least only egg production would be affected 2. cull 3. spend money on vet and try to get a better diagnosis if that's even possible with no discharge

I would cull but I'd like more assurance that this is really a Not Good Thing, and could wipe out lots of hens and mean no new hens til these ones die. I'd vastly prefer not to cull - my little son has fallen in love with them all and he's very tender hearted.

I appreciate anyone's bothering to read this far, and any thoughts you might have! Red Feather, Ginger, and my little boy and I await your wisdom...
 
If the only symptoms are the crackly breathing, and snoring sounds then its likely a disease called Infectious Bronchitis. If its that disease here is some information for you from my personal experience with IB.....

There is no treatment and its highly contagious. All the other chickens are likely to get it.

Ones that show no symptoms are likely to have had the disease in the past and now have immunity to it, but they will remain carriers for life. That is probably how the disease got to you your flock when you added (seemingly healthy) new chickens.

My advise is to let the disease run its course. If the chicken seems listless and is not eating much you should provide heat - this makes recovery faster.

There is little else you can do. I like to provide vitamins in the water and feed extra fattening food like the chick starter crumbs, just to boost the birds energy and immune system at this time.

When my flock had this disease some birds got better in only a few days, where others (the ones that had the mildest symptoms) took weeks to get better. All 20 of my birds recovered to full health and no deaths. I had little chicks too, but they never got sick.

In your situation I would not cull your birds - once they recover you can not tell they ever had the disease.

In large egg producing farms they will cull because it causes a drop in egg production. But in a small flock like yours the difference in egg production will not really be noticeable at all. My chickens stopped laying while they were ill, but now I get just as many eggs as before.

DO NOT add more birds to your flock or they will get the disease from your carrier birds. Then they will all get sick again - even the original chickens.

If you have a rooster you can just breed more chickens that will have immunity to the disease.

DO NOT sell or give away any of your chickens in the future, as that will spread the disease to other flocks.

IF THEY BIRDS ARE SHOWING OTHER SYPTOMS LIKE MUCUS OR RUNNY NOSE, WATERY EYES OR WATERY POOPS, THEY WILL HAVE A DIFFERNET DISEASE.
 
Wow, great reply, thank you!

Overall, your description is how it feels, but I still have a couple questions:

1. The Chicken Health Handbook refers to IB as having wet eyes and nasal discharge as part of the symptoms - we didn't, so is that just a matter of severity?

2. I read, and you confirm, that survivors have permanent immunity but become carriers. Since my RIR has had the same symptoms twice in 3 months, do you think she never recovered fully from the first round and it just got exacerbated again, or that this is a new strain of an IB causing virus (that she'll now be immune to also)?

3. I don't understand this part of your reply:
DO NOT add more birds to your flock or they will get the disease from your carrier birds. Then they will all get sick again - even the original chickens.
I thought that the permanent immunity would mean those originally sick chickens can't get sick again from the same virus?

Meanwhile, I'm so surprised that the acquired immunity in the adult chickens will pass to the chicks. That's great news.

I for sure won't pass these chicken along to anyone, but we will go ahead and add the 4 new that we've already adopted once their quarantine period is over. As I read that the IB causing viruses can transmit over 1,000 yards through air, I guess our current quarantine measures are really ineffective - something to consider in future chicken yard set ups.

If you have the time to respond to these extra questions, I'd really appreciate it. Your reply above was so helpful and resonantes closely with our experience thus far.

Cheers!

Maybe that does happen in some birds - but with my flock NONE of them displayed those symptoms. They only were making the rattily, snoring noises, breathing heavy, the worst ones would have great problems breather and stand still with their necks out and the beaks open (the worst effected got better the fastest, only being ill a few days - I thought that was interesting).
If they are having nasal discharge and wet eyes I would say its corzya disease. They will also have a bad smell to the face - it stinks!


2. I read, and you confirm, that survivors have permanent immunity but become carriers.

From what I understand they have a limited 'immunity', more like a RESISTANCE to that disease.
When new birds are added, the new ones have no resistance and so get the disease.
Once the new ones get sick, the old ones again pick up the illness from them. I think its because the disease virus increases in number a lot with all the sick birds and the original ones are overwhelmed. Also adding new birds brings stress to the flock, and stressed birds have weaker immune systems. It might be that the disease changes a bit each time - like the human cold virus - so once it flares up again, the other original birds get it again.


3. I don't understand this part of your reply:

Yes they can - like I say in my above answer.
Meanwhile, I'm so surprised that the acquired immunity in the adult chickens will pass to the chicks. That's great news.
It does not really pass on from the adults like that. Chicks are much more resistant to this disease than adult birds. As they hatch and grow up in the flock, they will pick up the disease and their immune system will be able to fight it off without the birds becoming sick. Then in the future they will have a greater resistance to the disease.
Also any adult bird that did die from the disease would not lay any eggs, so only resistant birds will reproduce - so having more resistant young.


I for sure won't pass these chicken along to anyone, but we will go ahead and add the 4 new that we've already adopted once their quarantine period is over. As I read that the IB causing viruses can transmit over 1,000 yards through air, I guess our current quarantine measures are really ineffective - something to consider in future chicken yard set ups.
Hopefully these new birds have had the disease already - maybe they passed it to your original bird on their arrival. If they do get it you will have to just provide good feed, shelter and vitamins.
Good luck!

I really appreciate your thoughts and time jak! In the absence of a crystal ball, I'm going with my gut feeling and your experience, and I've put the two recovered hens back in the yard this morning with their old flock. They definitely approve of this decision themselves - I guess our luxury bathroom accommodations were wearing thin for them too.

I really feel that I got thoughtful and clear help. I'm grateful!
 
My pleasure. I like to help others because I found it had myself when my chicken were sick.

At one time they just had a real run of bad luck and got one disease after another and I was on the point of getting rid of them and giving up keep ing chickens. It was only through helpful people on here that kept me going. Now my birds are very healthy and reproducing like crazy. I sell the young birds to local shops and keep the ones I really like. I have Japanese Bantams.

This is what happened to my chickens
scaly leg
fowl pox
feral dog attack (killed and injured many)
Infectious bronchitis.

Then a neighbors fighting rooster got into my garden and run and attacked my roosters and then my roosters kept attacking each other as they got stressed out.

Now every one is fine, happy and healthy.

I get so much pleasure for my 'pets' that I am very thankful that I kept going and did not give up. I keep my flock as they are - letting them reproduce, and I will NEVER add new chickens because I just know they will bring in some new disease lol.

Hope your birds do well. Don't worry about them too much - I found out that chickens are very very tough creatures, providing they get proper shelter, food and a stress free environment.

Nice if you can post a few pic of them on here.
