Im so sorry. But you gave me hope! 50 chickens after Marek’s diagnosis! Thats def good news. Can I ask you.. the pattern in loss? Like would you lose one then get a break for a week then lose another? Its so weird the way theyre going. I know their symptoms can be at rest then boom you lose one. But theres like no rhyme or reason in the way they’re going. I’ll get a break for a week lose one then ill get a break for 2 weeks or something lose another. This time I got like a little over a month without losing anyone I was naïve to think maybe that’s it we could be in clear(or I had to make myself believe that) then boom lost my Brahma Mama the other night. I kept saying she looked off in the eyes and usually with every bird I lost when I had that feeling they passed. How long until you stopped losing any? Did you end up waiting awhile before expanding ur flock? Did you vaccinate? Sorry for all questions just dont know anyone who's dealt with Marek’s too.
I started losing birds when they were about 14 months old. After losing the first bird I had a bit of a break. Maybe 8 months? Then I started losing birds at the rate of one a week, sometimes 2. The weird thing with mine is that they always seemed to go feet up on Sunday. I started dreading seeing Sunday roll around.
That lasted for about 2 years then I started getting breaks. Not long breaks, a few months maybe then a couple more would die.
One one of my second generation Buff Orpingtons, Welsummers and Speckled Sussex's survived to be 3 years old. I had 7 original hens survive. None of my original roosters or their offspring lived past the age of 2.
I've been 'Marek's death free' for three years now. I just lost a rooster and Egyptian Fayoumi hen to some sort of either infection or parasite load that caused sour crop and infection that I couldn't get under control but I do not connect their deaths with MD. The rooster was from resistant local stock and the EF hen had genetic and vaccine immunity. I think it was just a fluke of luck that they both died from the same thing so to speak.
When did it end? Suddenly 3 years ago after I made the painful decision to cull my original flock. If I could have bred resistant birds from the survivors, I would have kept them but like I said. In three years of them breeding like rabbits, on one of their subsequent generations survived and that was a hen. By that time I had lost close to 40 birds.
I added two vaccinated OEGB BBR hens to my flock when I needed emergency chicks to keep a loan chick company when mom rejected it. They are 5 years old now and plugging along, still laying. I hatched some daughters from them in April.
Then I added 5 Egyptian Fayoumi chicks to my flock three years ago. Just hatched 6 eggs from them and those chicks are now almost 3 months old.
I am seeing resistance in my vaccinated birds progeny which I find notable. Does the hen pass resistance on to her chick? I've read some studies that voice that possibility.
More interesting is the fact that out of the Neighborhood Amish Barnyard mixes I hatched I only lost two to suspected Mareks' Disease. As I wrote in my article. I let them breed at will and brother did they have a lot of will thinking that I might have a few live to produce eggs or viable offspring. One summer night my husband found me standing outside the run staring at them running around the run chasing bugs, healthy and fat. His first suspicion was that I had one that I had on Death Watch. I told him. They aren't dying? Why aren't they dying? He shrugged and said 'I don't know but you sure have a lot of birds'.
It dawned on me that those eggs came from an Amish farm within the five mile radius of our farm so well in the contaminated zone for the strain of MD I was fighting. I was looking at natural bred resistance! Everything started to make sense and it was then that I decided to cull the remaining birds of my original flock.
My oldest surviving bird, Old Man died this spring. He was 5. I let him out one day to free range and he escaped to the neighbor's timber. He never came home. Indy is now my longest surviving bird. He is one of the second clutch of Amish eggs that I hatched and he is also just 5 years old.
I've been experimenting with my EF hens and rooster to see if cross breeding them to the Amish barnyard hens would boost their bred in resistance. So far I haven't lost any other than two cockerels I butchered for aggression.
As a rule EF roosters are gentle. The Amish barnyard birds have Game Bird genes in them and those genes are proving hard to breed out of them.
I hope I've helped and answered all your questions. Like I said. If you can hang on, it does get better. But while you are hanging on, formulate a plan and do some experimenting.
