Recently , my married man found our Gold Laced Wyandotte rooster , Hercules Mulligan , lie near the provender binswithout a fool on him . He was fine the day before , and now he was gone .
Why ? We did n’t have an answer for this chicken expiry apart from the fact that he was walking oddly for several month .
We ’ve continue chickens for almost 20 geezerhood now , and we ’ve faced exchangeable event before . But it ’s always upsetting . As common , we began to inquire what had materialise . Could we have done something about it ? Would more death follow or was this a one - off ?
To get some reply , I turned to Yuko Sato , DVM , from Iowa State University .
Little or No Warning
It ’s unmanageable to empathize why a poulet expect healthy one day and experiences expiry the next . Sato says that this is because snort are prey animals , and so they have to be stoical about how sick they are until they are just about to die , which makes treating them difficult .
Some signs let in :

Getting Help
Can you call a veterinary when you have a sick chicken ?
You certainly can , if you may find one . domestic fowl veterinarians or livestock veterinary surgeon who bed how to address domestic fowl are few and far between .
“ I offer an elective course on backyard fowl wellness for veterinary students , ” Sato says . “ But most students contemplate poultry are interested in working in the industrial side . So field visit to hobby farms are n’t very common . ”

There is aid available , however . The Association of Avian Pathologists has information for chicken owners like us . you’re able to also touch your official state agent through theNational Poultry Improvement Planhas a list of officials within your body politic .
NPIP is also utile for information on chicken wellness . It monitors diseases that involve chickens : Salmonella typhoid , Salmonella enteritidis , Mycoplasma gallisepticum , Mycoplasma synoviae , Mycoplasma meleagridisand avian influenza .
Most states have a healthy bird aid line , too . you’re able to also necessitate for help if you ’re odd about why your chicken die , if you ’re worried that it ’s something that will spread to the other chickens or if you assay a way to prevent the same dying in the future .

You ’ll belike have to pay for a postmortem . Sato says to account wimp deaths to your state factor if you have had multiple death within a little span of time .
A postmortem examination can help you determine an unexplained wimp death .
Primary Causes of Chicken Death
Sato enter in a study calledCauses of Mortality in Backyard Poultry in Eight States in the United States(Kyran J. Cadmus , Ashe Mete , et al . ) . The study used autopsy answer over three long time from symptomatic laboratory in multiple state ( Hawaii , Texas , Georgia , South Carolina , Pennsylvania , Iowa , Colorado and California ) to infer how hobby - farm chickens die .
The finding demonstrated the grandness of educating owners on disease prevention and biosecurity practices .
No. 1 Cause: Cancer
Researchersfound that 42 percent of poulet human death were causedby cancers . Of that percentage , 63.4 percentage was due toMarek ’s disease or leucosis / sarcoma radical .
Marek ’s is a highly communicable fatal disease characterized by T - cellular phone lymphomas and peripheral nerve expansion , according to theMerck Veterinary Manual . poulet are the natural hosts for the virus . As such , Marek ’s is a worldwide problem , with every flock take for granted infect .
Only rigorously managed pathogen - free passel are gratis from the computer virus .

“ Marek ’s is make by a herpesvirus , ” Sato says . “ The computer virus gets disgorge in feather dander , and it ’s insufferable to clean that out of your hencoop . If it causes Crab is another story because there are three types of Marek ’s and only one cause cancer . ”
The other two character of Marek ’s are used for the vaccine serotype 3 or HVT . The two type of Marek ’s are the same computer virus , but because they are noncancerous , the vaccine is very good . However , serotype 3 does n’t induce the immune system of rules as well as the serotype 1 vaccine , gain from the cancer - causing type .
Sato say that this character is undermine so it is n’t harmful . But because the vaccine is a living computer virus , it ’s difficult to keep ( it has to be stored in liquified nitrogen ) and expensive . So it ’s ordinarily given to commercial fowl , although some large hatcheries practice it .
Here ’s what to do if you go through the destruction of a chicken during the wintertime month .
What You Can Do
When you purchase your chicks , ask the hatchery if they offer a Marek ’s vaccinum and , if so , which one . Also inquire about vaccinations during chick day at your provender - provision or big - box store . Do n’t assume it as a given .
If no one at the storage knows the solution , assume the chick are unvaccinated . If you decide to purchase the birds disregarding , understand that your new chicks will have no immunity to the disease .
dame have to be vaccinated before they are 1 daytime old because the vaccine will not work if the shuttlecock has already been exposed to Marek ’s . The vaccination be about 20 cents a hoot , so it ’s not deserving skipping . In some of the bigger producer , the chicks are vaccinated in theegg .
Additionally , Sebrights and Barnevelders are more susceptible to the disease than other strain , such as Marans and Sumatras , which very rarely shrink Marek ’s .
regrettably , vaccinated chickens can sometimes reduce Marek ’s as the computer virus can overwhelm the vaccine or because the vaccinum has been give improperly . Marek ’s can light upon a bird at any microscope stage of life .
“ A 2 - calendar month sometime chick can get lymphoma due to Marek ’s , ” Sato says .
Ovarian Cancer the Crab make up 27.8 pct of this No . 1 family . “ genus Cancer is any cellular phone multiplying out of control condition , ” Sato pronounce . “ A position biddy ’s ovaries are always fighting . fervour can set in or a reaction can chance , and from there cancer can develop . ”Elena Masiutkina / Shutterstick
Infectious Disease
More than 36 percent of fatality in backyard birds staunch from infectious disease ( from bird to bird , not from bird to human ) .
Bacteria accounted for 34 percent of the full pct . MG ( Mycoplasma gallisepticum ) and MS ( Mycoplasma synoviae ) answer for for 26.1 percent .
MG is also hump as inveterate respiratory disease . fowl with MG might not show symptom at all , but some can . signal can include sneezing , nasal and heart discharge , and rales ( rattling go in the lung ) .
MS dissemble the respiratory system , but it can also strike the joints . In addition to the same symptoms of MG , MS septic birds can march stiff motility , conceited joints and lethargy .
septic chickens carry the disease for their total aliveness . Contaminated equipment , wild birds and rodent can carry MG and MS , so biosecurity and cleanliness is important .
Viral infection ( again , from bird to bird ) , accounted for 7.3 percent of the total number . IBV ( infectious bronchitis virus ) is a very catching ( for razzing ) coronavirus that causes tracheal lesions and upper respiratory disease . It affects the poultry industry widely and was the top computer virus found in the study . Symptoms include sneeze , coughing and rales . IBV is very hard to control .
Generalized Noninfectious Diseases
More than 16 percentage of the cogitation was vulgarize noninfectious disease . Of these , fatty liver hemorrhagic syndrome was the top perpetrator . This syndrome only affects hens and is thought to be triggered by overfeeding .
It may also be because of a calcium lack , stress or feed contaminated with the mycotoxin aflatoxin .
Withfatty liver haemorrhagic syndrome , the liver becomes fat , and as a result damages easy . human death appears when the liver ruptures and causes interior hemorrhage . This commonly take place in caged laying hens .
you’re able to help prevent this disease by offer atomic number 20 to the diet , deepen provender and baffle food usance .

Public Health Concerns
The study found that 1.6 pct of birds died from zoonotic bacteria ( bacteria that can remove to humans):Paratyphoid salmonellae , Mycobacterium avium , Listeria monocytogenesandCampylobacter jejuni .
They also found evidence of lead and other heavy metallic element , which can change to bollock and meat , and one case of botulism .
the great unwashed often worry about contracting influenza from their bird , but Sato cites a gloomy rate of that happening in the U.S.
“ We ’ve heard about mass in China and Hong King dying from bird flu , ” she says . “ But this is due to hoi polloi living in their houses with their chickens . ”
Sato says our rooster could have had a muckle press on his nerve , which caused that odd , high stepping pace . I felt relieved to realize we could n’t have prevented it .
In the end , we knew we had given our guy a place to know , with a flock of fresh biddy that adore him . He was a very lucky rooster .
disease due to poor management and nutrition only number to 9.7 pct in the study . you’re able to do your part to keep your chickens healthy by :
