Wonder how we or hatcheries decide we or they are truly breeding for resistance of any poultry disease unless the birds are actually having the various diseases introduced to the flock to see how they cope??
My thoughts precisely. I've read so much over the past two weeks that my head is swimming, but one article I remember reading speculated that if every chicken was tested you would find exposure to Marek's in every bird. Now THAT is scary.
 
@microchick Yes, I think pollen can nearly kill you...almost. It certainly feels like it...lol. If it's going to be a year where it bothers that much, you may find it helpful to make a pre-emptive strike by taking the allergy meds prior to exposure. I take them 100% of the time, as soon as they begin to wear off I know immediately. Hopefully once summer's underway yours won't be a bad.

@superchemicalgirl Curly butt feathers? That's just too funny!

Herpes virus - better to not catch it in the first place, but once exposed...it's better to have strong, healthy stock is a must to keeping sickness and death down. This is sort of like the orf virus in sheep. It tends to show up when sheep are stressed and/or when new animals are exposed.


@Beer can That's a good read! I would get along well with the Wolf family. The ideas presented regarding resistance and selection of birds, or lack there of makes total sense to me. I will be reading this as well.



The one issue with the idea of breeding for resistance/creating a well rounded bird, productive bird is that not only would it take years of selection (which is fine) but even when you reach your goal, you have no one to obtain stock from without losing ground unless you have a collective of breeders who can decide AND AGREE upon the list of specifics that are the end goal. I found that with the sheep. Sure by 8-10 years of breeding I'd eradicated dominant and recessive faults, improved lambing percentages, lengthened lifespans, improved docility, rate of gain and meat to bone ratio...a well rounded animal with desirable traits. BUT to source an outcross ram from another breeder...that sets your breeding program back years. That's within a purebred breed within a set guideline of standards.

Even with the cattle it has taken us 8 years to get where we are and there are only 2 breeders for certain...possibly 3 that I could, with confidence, go and buy another bull from and expect it to enhance what we have and not introduce issues. It's simple economics. People don't want to cull an animal that's substandard if they can make money instead. It's incredibly expensive to take the time to properly develop a breed or a particular strain because culls don't make the money breeding stock does. And not everyone has the same standards. I can't even begin to tell you how different my views are from most regarding the simple aspect of hoof trimming in bulls...lol. Everyone looks at me like I'm insane! Maybe I am.

Chickens have so many different breeds and types etc...it would take a pretty dedicated and like-minded group to achieve a breed/strain of chicken that stands above and beyond within certain parameters that carries disease resistance. Now that's something I'd want to be a part of.

I contacted a hatchery up here regarding testing for diseases etc. Their response was that all their breeding birds are tested for the diseases I asked about...as are all federally registered hatcheries. Mareks was one of the diseases.
 
Interesting to note @microchick
remembered reading this somewhere, it was in a link in the beginning of sally's thread.

Not mareks but Ideal poultry pretty much saying they nor any hatchery they supply and possibly many, are mycoplasma free and not required to be. It was also mentioned Hoover Hatchery and Murray are mycoplasma free and test monthly.
