Why are my friends chickens falling over and dying?

I don't have pictures, but I did see one in action so I'll do my best to explain symptoms.

My BFF bought 25 California whites from a local "breeder". Fairly recently they have been dropping like flies.

The first symptom is a droopy tail. Most of the birds have upright tails, but the ones who get sick have tails that point downward.

The second symptom is partial paralysis(?). One wing will droop and they will walk like a drunk, falling down and laying there for a while, not even caring if another birds steps on them. This gets worse as time passes.

Lastly she has been finding rubber eggs (no shells) which she thinks are from the sick birds. She has felt inside their vents and does not feel anything. Says poop looks normal. She has not autopsied the dead.

The Chickens usually last 3-6 days after first symptoms appear. Chickens started laying ~2 weeks ago (AGE). They die one or two at a time. None of her other chicken breeds who are older (1-2 years) have become sick so far.

Does this sound like anything to you guys?:confused:
I will post more info when I get it. Thanks!

UPDATE#1: Text from BFF: "Chickens have no respiratory distress symptoms, just beak gap. No gargling, no heavy breathing. Like they hold their mouth open funny, but not cocked back. Their crops are full and night and empty in morning. They are empty all the time the day or two before death, but it is because they don't leave the barn at that time. The partial paralysis has not been as prevalent with the last two deaths. We speculate it's a genetic variant, but don't know."

Chooks have been given probiotics and calcium. They eat layer feed with 18% protein and have access to grit and oyster shell as well as free range.

A necropsy would be indicated with repeated losses. Mareks is the most likely explanation, especially with one-sided paralysis. Things like aflatoxin (mold) poisoning, botulism, lead or chemical poisoning tend to cause general paralysis of both sides. Botulism starts in feet and legs, progressing upwards in the spinal nerves, and the whole body is quickly paralyzed over 12-24 hours ending in death. Dehydration or coccidiosis can cause lameness or wing droop that may look like paralysis. The owner needs to get a necropsy that includes Mareks testing, but I would also look at feed, water and waterlines, and have a look around the ranging area for plants or other things that could affect them. Egg shells may be affected by viruses such as infectious bronchitis. Mareks can cause a poor immunity to common illnesses, so they can be affected by everything in the environment.
 
Classic Marek's Disease symptoms. And for pullets, at time of beginning to lay, is most usual time to express the disease. Sometimes after the first egg! There is no treatment, so do not waste medications. Many will eat and drink if they can reach food and water, but paralysis is gradual and when neck and area means they can no long eat or drink--it is usually a quick ending. Be assured that it is not painful for the bird, just frustrating to try to stand and move. First time that limp on one leg appears, we are sure they are hurt--but chickens rarely hurt their legs (can fly from a rooftop and not hurt legs). Then wing on same side becomes useless--and the bird is down, scooting, if possible. A few recover--lay (and Marek's is not carried in the eggs, so they are truly safe to eat! But they are carriers, then, for the long lived VIRUS (not treated by antibiotics for Bacterial infections). Very sad and I am truly sorry for your losses. AND the virus will be with you for a L O N G time. Best to renew your flock with vaccinated chicks or hens. Good luck. (Been there..)
 
Honestly that's what I thought, but she INSISTS it's not Marek's. Hopefully I'll get some more opinions on the matter.

Just curious, but why does she insist it isn't Marek's?

Might be a good idea to start with a fecal float... see if she can collect as many different samples of their poop, mix well in a baggie and find a vet willing to check for cocci and worms... certainly sounds like Marek's, especially since the flare up sounds like it happened right around POL... stressors bring up outbreaks and laying is one... but wouldn't hurt to rule out cocci or worm overload...
 
@venymae I'm sorry to hear about your friend's chickens. I can only assume your friend is located in Kansas. It really is a good idea to have some testing performed to find the cause. Here is your state lab information:

Kansas State Veterinary Diagnostic Lab http://www.ksvdl.org/
Client Services at (785) 532-5650, toll free at 1-866-512-5650
 
She needs to send one off for necropsy. The symptoms really do sound like Marek's, but a necropsy will verify it one way or the other.

I saw this asked earlier, but I didn't see it answered, why does your friend insist this isn't Marek's? Is it because she has a good reason to suspect it's not, or is it just because she doesn't want it be?

Rubber eggs, if truly shell-less, can be nutrition related (i.e. D3, phosphorus, calcium, manganese), but since none of her other birds have a problem, it is most likely disease related. In fact, feeding additional calcium may do more harm than good.

Newcastle disease, IB, AI, Egg drop syndrome and many other diseases can cause this issue. A necropsy with lab work will tell.

I'm not sure how someone can insist it's not Marek's without lab work or even a cursory necropsy. Marek's can have a wide range of symptoms or sometimes none at all - just sudden death.
More chickens die from Marek's virus than any other disease. It is so common that one can safely assume their chickens are infected whether they show symptoms or not.
Some birds carry the resistance factor B21 and breeding for resistance is the best defense.
Stress will reduce a flock's resistance. That can be from crowding, moving or the natural stress from maturing. That's why 10-25 weeks is the optimum time for the disease to represent and why chicks shouldn't be raised with adult birds.
The six herpes viruses that cause Marek's survive in dust and litter for years.
If it is Marek's, your friend may want to do nothing more than cull affected birds. The rest will be resistant. There is no cure once succumbed.


Hey I contacted Kansas State University, who does necropsy's in my State and they said they don't test for Marek's themselves but they send it out to a lab. It's $12 to get the necropsy and $60 to have it sent to the lab for Marek's testing. :eek: Does anyone know of a lab I could directly send it to instead of going through KSU?
IMO, that's pretty reasonable. In MO, I pay between $75 and $100 for a complete workup of the bird. It is well worth it to know what killed a bird, what actions, if any, I need to take and whether other birds are at risk.
One can bite the bullet and pay for the necropsy or chew gum and watch birds continue to die while guessing and stabbing in the dark.
If I have one bird die, I either do a cursory necropsy myself or what I usually do is send them off to Columbia, MO. If I had more than one bird die in short order, I'd definitely get the lab work done. I've driven the 6 hours round trip several times (sometimes all night) to take a live bird there for euthanasia and necropsy. If the bird is dead, they will send me a FedEx label for shipping. They will add that reduced cost to the necropsy bill.

If your friend is unable or unwilling to opt for the necropsy, they should at least cut the bird open. Of the 4 forms of Marek's, the skin form will cause enlarged feather follicles. The nerve form (likely) will cause progressive paralysis, labored breathing, diarrhea and weight loss. The ocular form will cause misshapen pupils, grey iris and emaciation. The visceral form will cause tumors in most organs, especially lungs, ovary and heart along with enlarged liver.
