Has anyone here crossed Speckled Sussex with Buff Lace Polish? Wondering if i can breed for Mareks resistance.

I have read (but off the top of my head I can't quote the source) that resistance takes years to prove... MDV is kind of like the chicken pox virus that can stay dormant forever until, whalah! Shingles!!
Before the MDV vaccine, there was a very concerted effort in the poultry industry to create resistant birds - I'm trying to remember the exact problems they ran into, but I know that one was birds that were more susceptible to other viruses, and the other has to do with similar chromosomal make-up creating weakness (inbreeding issues).
All that said, I know that folks are definitely working; breeding their seemingly resistant birds. The problem is (and I'm going to sound like a real downer here -sorry) Marek's can strike at any age (even though under 25 weeks is it's prime time), so knowing if your birds are truly resistant or just carrying dormant virus is a toughie.
Sigh.

Well those 2 breeds are what i have. They were all supposedly vaccinated for Mereks at the hatchery. They hatched mid August. I had 10+2 , female and male of each breed supposedly. One extra polish ended up a cockerel. So far i lost one polish cockerel, 1 sussex cockerel, and 4 sussex pullets! 25% of my birds already. I am pretty much stuck as you know , even if i culled all of them you can't sterilize everything. So i thought it might be interesting to cross them and see what i get. Doesn't matter if they are not saleable since i will not sell them. Curious to what i will see in the mix.
Thanks for answering Orr.
