Hi ,I'm not sure if its this, but i know i heard this some time ago if you raise turkey poults with chicken chicks the turkeys are more Resistance to something it may be mareks..
what ever it is the poults help strengthen the chickens immunity to it,, somebody might know right of hand. i just cant remember what it was.. old age is getting the best of my brain..

Turkeys carry a form of Marek's disease that does not cause symptoms in turkeys or chickens. The turkey virus is used in creating chicken vaccines. Some believe that raising turkeys & chickens together will effectively vaccinate the chickens through exposure to the turkey droppings.
However, this has nothing to do with breeding for resistance.
Breeding for resistance to Marek's or any other disease involves culling any bird that develops the disease and only breeding from birds with natural immunity. This system works very effectively for anyone willing to cull infected birds rigidly. When you nurse a bird through a Marek's infection, some will survive, you are left with a Marek's carrier that will infect all your other birds.
Fred Jeffery, who wrote a book on poultry diseases, advocated this system. Mr Jeffery said his medicine cabinet contained only a Coccidiostat, louse powder & a hatchet.

Thanks NYREDS , thats what it was then..

also one thing to remember,, is suppose you never get Marek's or any other diseases, which we all hope not to... you wont be able to breed for Resistance..

however if you buy birds that had the vac for it, they may give it to other birds in flock that way,, as i beleive the mareks vac only masks the disease or somthing of that nature....

Not all vaccines will give other birds mixed in your flock the disease. I know there use to be a chick origin ILT vaccination that would spread to other birds not vaccinated. Now they have a new one that is tissue origin I believe and it doesnt spread bird to bird LT-IVAX. Some people have vaccinated there birds around where I am due to a recent outbreak at a farm. Here in Wa they will depopulate your flock. So, that is why I chose to vaccinate. I know some people think less is more and I respect that. I have to much time and money invested in my birds to lose them to a vaccinated-able disease. I wouldn't let my kid walk around without his vaccinations why would I let my birds? I don't vaccinate for everything, just high risk things in my area. I've done a lot of research and in my case the pros out weigh the cons......Okay, thats my 2 cents

This is something I have read. Some chickens have a "B" factor in their blood that makes them resistent to mareks disease. Is is said to be desirable to breed from these birds if you have access to a lab that can test for B factor. I thought this was very interesting and something I want to look into. I think it may be something like a herpes virus that attacks dogs and kennels. I had a dog bring it in once years ago and some pups in the litters died, and others never became ill at all. A pathologist suggested they may have something in their blood that made them immune and are the ones you would want to keep to breed. I am thinking that may be the same with the chickens since mareks is a herpes virus. I guess breeding for this resistance would involve building a flock that had this "B" factor in their blood.
