Yep. Wild birds spread carry these diseases everywhere.
And to add gasoline to a fire- I am not sure that culling a chicken that has survived a disease is doing Ckickendom any favors. In other words- How can we produce chickens resistance to these diseases if we cull them?
Dont jump all over me. This is JMHO.
I'm not going to "jump all over you". I am going to explain why this theory does not work biologically lest people are reading and thinking "Gee! We can keep sickly birds because they'll pass on RESISTANCE!"
Ummmmmm, no.
That would be great if that's how it worked, I suppose. It'd certainly be a whole lot more feel-good for those who like to save everything, if nothing else. Unfortunately, it just does not.
The first thing we have to understand to know why not is how exactly being sick results in immunity or "resistance" to that illness. When a chicken -- or any animal -- is ill the body creates certain antibodies to fight that disease off. In some cases these antibodies remain in the body for a long time after the illness has passed, ready and waiting, to attack should that particular nasty rear its head again. In other cases the body simply "remembers" how to quickly and efficiently manufacture these antibodies; it "learns" how to fight off the disease so next time it's faced with the disease it's able to fend it off quickly and easily. This is an exposure related resistance. It's resistance, but it's not a natural lack of sensitivity such as the resistance that you'll often hear people talking about breeding in.
There are a couple of reasons for this. The first and foremost is that exposure resistance cannot be passed on from chicken to chicken to chicken. It is due to personal exposure and that is the only way it can be gained. Each chicken must develop this immunity on its own. There is evidence that antibodies can be passed trans-ovarially, that is from hen to chick via the yolk in the egg, but these antibodies -- like the antibodies passed to other species in the same way -- are short lived. Most are completely gone by three weeks of life at which point the chick then has zero immunity to those diseases. Another important thing to know with this is that even when antibodies are passed on they're usually passed on in much smaller quantities than they are found in the hen herself which means the chick isn't even wholly protected on day one. He simply has a small amount of antibodies present that may or may not afford him a little bit of immunity. It's also important to know that not all antibodies are passed on to begin with. Antibodies against Salmonella, Infectious Bronchitis, Fowl Plague and a few others have been observed but there have been plenty of trials where none at all were observed as well.
The second is that exposure resistance is expensive. To have every chicken needing to get ill and then better again in order to capitalize on "resistance" is not an economic way to raise birds. In many cases carriers are the exception to the rule, the survivors and the mortality rate of the disease may be as high as 80-90%. Losses are expensive, treatments are expensive, ill chickens are time consuming. Aiming to create birds that will result in time and money down the drain is not effective. That's why we have vaccines, to artificially give exposure immunity to chickens who cannot be reasonably expected to have natural resistance. It's cheaper, quicker and more effective to administer faux exposure immunity than to wait for the real exposure immunity to take its course with one's birds.
Now, the type of resistance you would want to (and can) breed for is natural resistance; a genetic propensity to lack sensitivity to pathogens and a strong immune system to fend them off without clinical affliction. These are the chickens who never fall ill to begin with. Some call them hardy, some call it vigor. Whatever you call it they have a demonstrated ability to not just survive, but thrive. This is "survival of the fittest" because chances are your chicken with exposure immunity wouldn't have survived the disease without your intervention. These are the chickens that can pass their genetics on to offspring and be reasonably expected to create more of the same. Because their resistance is genetic, not created out of previous illness, it can be passed on to future generations.
This isn't to completely discount environment. There is strong evidence across species boundaries that indicates that an overly-sterilized environment leads to a compromised immune system. But there is also strong evidence that a genetic component for reacting in such a way that the immune system is boosted when exposed to pathogens, rather than afflicted with illness, plays a large role in the overall hardiness of an animal -- which includes humans.
lol This is the same thing I said you just used alot more words.
I never referred to building resistance by keeping sickly birds who dont recover. But breeding birds that do recover and ones that dont get sick at all. Your "natural resistance " paragragh. Old timers didnt cull their entire flocks. If they found them they culled the ones that were poorly and not up to snuff. Probably ate em. The survivors that never got ill or recovered were the ones producing the next hatch. Why do I say "found"? Cause on those farms the chickens free ranged everywere. If they got sick they either recover or died in the bushes.
But now when people talk about diseases they refer to culling their entire flock.
Again, is this doing chickendom any favors? Not only having these diseases spread by wild birds but more and more folks are getting chickens.
Having a closed flock will be next to impossible unless you are a chicken farmer with huge sheds to lock them in.
As you pointed out, we are the offspring of survivors. Our chickens should continuie to be the offspring of survivors.
I also am a supporter of vaccines. One of the more natural ways we can jump start the immune system against cocci and mareks.
AGAIN, this is JUST MY HUMBLE OPINION which I am entitled too and do not jump on me for it.

So Sad to think that his parents don't want him around!! Sounds like he's quite helpful and likes company. Probably lonely & dying for some paternal attention. It's also sad to think now a days we can't even invite or welcome someone into our home without always having our guard up....THANK YOU SICKOS!! He'll probably be crushed or hurt. If you invite him in again...just make sure someone else is present in the house.

Krisrose,
I do think you and Olive are actually on the same page.
I thought 'closed flock' meant that no new chickens come on to your farm to live or none of your chickens who are survivors of coccidia or respiratory disease leave the farm because they may be carriers. That seems like the only way to keep more chickens from getting those conditions.
If 'closed flock' means they have to be in buildings, then I misunderstood that term.

Closed flock is interperted differently, but to me you do not introduce new chickens or chicks. It can still be a closed flock if you sold your chicks/chickens. Nothing in. Other people only bring in new chicks and others will only hatch their own eggs.
What I meant by having to be locked in a chicken shed is this, with wild birds and several backyard flocks in your area, you would have to lockup your chickens to have a closed flock. I have at least 6 flocks within a mile of me. So even if I did not introduce new birds, the wild birds eating out of their food dishes will bring in whatever bugs those flocks have.

chickmate, do be carful as you said to many people are willing to accuse you of something you would never think of doing. Even teachers are not allowed to drive a student home or to an event. (especially one of the opposite sex.) NEVER be alone with a child that is not your own. Really is sad. Many yrs ago We lived in GR then. there was a boy hows mom or brother would drop him off at the park in the AM and pick him up later at night if they remembered. we often had him for dinner and on a few occasions over night. I called protective serv. once, they know the family; said I could keep him over night or they would come and pick him up and he would have to go to juvenile detention till they reached his brother. He will always remember your kindness though and maybe grow up to be a much better person then his parents.
Thank you, Teeville,
I was happy to get so close (10-12 feet). One really good shot before he took flight.
Being a nature geek, I shoot a lot of pictures and every now and again, I get a really nice one.

I am not trying to work anyone up. even if i do nothing at all these guys will pull through fine. I am researching the meds for people who want sterile flocks; if we could actually cure this instead of having carriers, those birds would be saved and it would end the great debate. I will not try ANY med without a lot of research because i do NOT want to give the wrong thing. I would prefer to find natural things to help them heal. Not being a hypochondriac. I really do have a whole flock of little birds that comes flying when they see me with the chickens. Had one land at my feet a couple of days ago! I guess they figure if i'm not trying to eat anyone, i'm safe
My little troop is eating fine (hogging, really) and pooping normal. I do feed them manna pro gamebird/showbird supplement every day, and i noticed that even when they got worms they pooped normal as long as i gave them that. It must boost them a great deal. Since this has all the vitamins and whatnot they need, i also feed them as much fresh produce as i can, along with their scratch, so this probably helps too. I have been trying to give them extra meat at least once a week since they all really miss the grasshoppers. I really can't coop them entirely because they are my garden helpers too. That's how they "earn their keep" We are plagued by grasshoppers. Also i'm fairly sure there is nutritional value in the weeds they eat, and better them than me! I just eat the eggs and reap the benefits.
sorry if i'm giving you guys heebe-jeebies! I have always been fascinated by dr stuff. I was talking about it all more in the spirit of giving hope than trying to be gloom and doom; not sure if ya'll are catching that? It would be sensless to buy new birds without knowing about all the risks and how to prevent them, and for the future maybe there will be a cure or that elusive resistance. Anyway, merry christmas and all from a celebrated scrooge.
and may all your hatchings, err days, be bright!

Fuzzy - all opinons are welcome to me and since chicken farmers in the past did not have internet forums we may be the first group to be able to track illness and prevent it.
