Hey there. just wanted to post where I'm at with a mareks battle:
Several months ago I wrote in and got some advice, have lived through marek's now, and want to re-tell my story. I had about 50 birds...silkies, layers, and crested polish. All started as babies, was into it 1&1/2 years, Then I bought 3 adult crested polish from a breeder/shower for $25 each. They were so cute, I just had to have them. Big mistake. They were the source and I now know I bought her rejects ( so to speek) that were carriers but resistant to mareks. One by one, month by month, my birds died slowly, mostly wasting with some paralysis. Towards the end I gave about 12 layers away to live out their dying days at a friends who had no problem accepting them disease and all, and I kept about 6 strong ones hoping they would be fine. Then a couple of those wasted too so I made the decision to cull the rest (this stunk) and try to start over. I pressure washed my chicken house inside and out. Then I sprayed it using a backpack sprayer with liquid lysol and water to the point of runoff. Then I pored both hydrolized and garden lime over walls , floors, and the outside pen. Some of this I tilled in, some not.. There are still some chunks of the hydrolized lime out there because it was caked and never really mixed in all the way. Then I shut down this coop and let it bake in the sun over June, July, and August.
Meanwhile I was raising chicks from the old birds that I culled, and bought some new ones online which I had vaccinated. Plus I bought some more at the local feed store. I raised them in a new place, up wind from the old coop. At the end of August they were between 4-8 months of age and I moved them into the old coop. It's October now and there are no signs of Mareks (fingers crossed).
All are healthy, eating well, and no one is acting strange. Could I have kicked this disease out??? I hope so. Culling was not easy, so I hope I made a corrective decision. I'm hoping that a live carrier is more of the cause then shedded virus in the soil and surroundings. Just wanted to share. We'll see what happens in a month or two.
