Marek's again . . .

About a month ago, I lost two 20-week olds to Marek's--at least the vet and I were pretty sure that's what it was. I knew that the virus was in my flock, but ALL of my hens had been vaccinated, so I was hoping for the best. I now have two older hens who have just reached the POL, and they are exhibiting signs of Marek's, too. I know I ought to euthanize them before they begin to suffer, but I just want to be sure . . . . I guess I'm looking for reassurance.

Symptoms? These two came into my flock together as six-week olds. they are a welsummer and a wynadotte. The Wynadotte, Dottie, has been laying for about two weeks, and the Welsummer, Summer, has just begun the submissive squat.

Yesterday I first noticed Summer--she was walking as though the sand in the run was slippery ice--she'd put a foot out, then withdraw it as if she was afraid of losing her balance. When I saw her trip over a wire frame she should have been able to leap over, I knew. I put her in my isolation coop, then I began to wonder about Dottie. She's a huge, PUFFY, chicken, and when I watched I realized I could barely see her feet. She wasn't moving much at all, and when she did move, it was more like she was walking in a squat. So even if it wasn't Marek's, I thought I'd isolate her, too--and Summer could use the company.

My isolate coop is a small, "two-story" affair, and I thought they'd spend the night on the bottom floor. But this morning I found them in the safe, sheltered top floor, so I knew they were at least a little agile. But I waited and waited this morning, and they didn't come down, so I thought they might be afraid to come down to their food and water. I manually moved them down to the bottom, where they ate and drank as usual.

But as I watched them in the small run (right before it began to rain, so I moved them inside again), they were still moving like they did yesterday--Summer with mincing, unsure steps, Dottie in her odd "squat-waddle."

Sound familiar to anyone? I have baby chicks in my office I have vaccinated twice--once, and then seven days later for a booster--and pullets that were vaccinated at the hatchery (as all of mine were). Of my four hens I think are Marek's, all the symptoms have been associated with walking. No weird visible tumors or eye problems.

Sound familiar to anyone?
 
There are different strains of Mareks. To me it doesn't necessarily sounds like Mareks, especially since you have 2 exhibiting symptoms at the same time. I would wait and watch. Is it possible they ate something they shouldn't of, or ate moldy feed?
 
I don't think so. The feed is fresh and they don't free range, so they don't really have access to anything they shouldn't eat. I checked them today and their condition hasn't changed--still wobbly on their feet. :-(

I'm sorry to hear you lost a couple last month.
What type of food/treats do you feed?
Photos of you coop/run and how much space you have?
A video of their actions would be great - upload to youtube, then provide us a link.

You mention you knew you had Marek's in your flock - did you get a necropsy or testing for necropsy?

last year I had a few even paralyzed chickens. it wasn't marek's but they were overloaded with round worms.
 
Update: Today when I went out to check on my two sick girls, I saw at once that I was wrong about Dottie--it wasn't Marek's, it was a pretty nasty case of vent gleet! Fortunately, I knew what to do, so I brought her in, gave her an Epsom salts bath, and clipped the yucky stuff from her tail feathers. She was a little prolapsed, so I pushed her vent back in and applied Preparation H, then put an anti-fungal cream over her vent area. Then I gave her ACV in her water and put her in her nice quiet hospital coop.

Summer, on the other hand, still looks like possible Marek's, but I ordered a dewormer just to cover that base. Pretty sure it's not coccidiosis, because her stools are normal. But Dottie is now on the treatment plan for vent gleet, and Summer--I'm still watching her. Thanks for your input! dottie best-_AHP2571-2.jpeg
