disorder of the nervous organisation can do skirt to pretend in unnatural — and often scary - looking — ways . Typically , you ’ll see the header turned or twisted in an odd direction , a condition normally come to to as “ crookneck ” or “ wry neck . ”
The expert Scripture for perverted cervix is “ torticollis , ” from the Romance Word “ torquere , ” meaning to twist , and “ collum , ” intend neck . When wryneck is not a steady pull , but occurs in abominable muscle spasms , the technical term is “ opisthotonos , ” a Grecian parole meaning “ drawn back . ”
skirt experience nervous systems upset also may appear uncoordinated , faint , staggery or paralyzed in one or both leg .
If depart uncorrected , the neurological disorderliness may lead to trample of the inauspicious doll by incubator mates or personnel casualty of the ability to eat and drink . The five most vulgar condition that induce wryneck in chicks are :
Congenital Loco
Congenital loco is an inherited disorder because of a recessive factor . It appear in chicks at the time of hatch .
Unless you hatch your own eggs , you are unlikely to see this circumstance . An affected chick ’s cervix twist backward . This give the chick off balance and leaves it ineffective to consume intellectual nourishment or water .
Although this status appear to result from an inability to control the neck muscle , a few studies have indicated it may be triggered by a defect in the ear social system . bird feel inborn loco seldom survive more than a few days .

A deep condition also predict “ inborn loco ” occurs periodically over a period of a few days , then go away as mysteriously as it get along .
This condition bet monovular to congenital loco . But the fact that it does n’t appear at the time of hatch and is n’t lethal indicate it may be a separate and unrelated issue , with an as - yet unknown cause .
To flurry things further , this mystifying term is sometimes called “ stargazing . ”Gedeminas777 / Shutterstock

Stargazing
Stargazing is a nervous organisation disorder that will causes a skirt to turn away the neck opening so far backward that the head teacher meet its back . The beak will luff skywards — hence the name “ stargazing . ”
The epileptic - like muscle spasms that pull the head back typically have the bird to tip over . After a few days of struggling , the chick will die from lack of food and water .
This term typically appears in chick less than 1 hebdomad previous , due to vitamin B1 ( thiamine ) deficiency in the diet of the chick ’s parents . bet on the severity of the want , the chick may recover if given a vitamin B1 add-on .

Crazy Chick Disease
Crazy chick disease resembles stargazing , except stargazing chicks stop eat up . Chicks with the disorderliness continue to consume despite their dire condition .
The schematic name for unbalanced chick disease is “ avian encephalomalcia ” ( from the Greek words “ enkephalos , ” meaning “ mastermind , ” and “ malakos , ” intend “ soft ” ) .
Encephalomalacia is a softening of the brainiac tissue paper that , if not treat ahead of time , solution in permanent brainiac damage . An moved dame may stargaze or pull its headspring down between its leg , often twisting the head to one side .

This perspective invest the chick so far out of correspondence that if it test to walk it tumbles over .
The primary effort of this disease is a lack in vitamin atomic number 99 , giving the disease its other formal name , “ avitaminosis E. ” The vitamin may actually be present in the diet but unavailable for metabolic process .
For example , when vitamin E is furnished in the shape of polyunsaturated fats — such as seedcase liver crude oil , corn rock oil , soya oil or wheat source oil — that have become rancid , the vitamin oxidizes and is no longer available for preoccupancy .
Chicken actually require very little vitamin E requirement . This experimental condition is therefore unlikely to come where stock breeder spate rations and chick starter consist of appropriately formulated fresh rations .
A breeder flock ration deficient in vitamin E results in chicks that exhibit crazy chick disease within a hebdomad of crosshatch . If wench train this condition because their starter ration miss sufficient metabolizable vitamin E , signs will appear within two weeks of being feed in the deficient diet .
Without discussion , the skirt ’s brainpower eventually deteriorate to the extent that the skirt can no longer function , whereupon it dies .
When started early enough to avoid serious damage to the brain , an in effect discourse is to add 1⁄2 teaspoonful vitamin AD&E powder per congius of drinking water until signs go away . PeterVrabel / Shutterstock
Head or Neck Injury
Torticollis is not always due to disease but may leave from a puff to the head or neck . Head injuries that chair to nervous system disorder are coarse in tufted breeds . These tend to have skulls that are less bony than noncrested breeds .
If the crested skull bone does n’t entirely envelop the brain — because of genetic science or an injury — a reversal can cause the genius to swell and press through the skull ’s gap .
A wench with such a headspring injury may tuck its nous down between its legs and perhaps move backward until the bird backs into the incubator wall or other obstacle . look on the extent of the injury , the stipulation may be temporary or permanent .
When enhance chick of crested strain , providing a dependable brooding environment is essential .

Marek’s Disease
Unlike other nervous organization disorders of wench , Marek ’s disease is because of herpesviruses that replicate in plumage follicles , are cast off in dander and survive for a year or more in coop junk . Chicks acquite this highly contagious disease ( which does n’t affect humans ) when wimp inspire contaminate dust or dander from infected birds .
The disease — named after veterinarianJózsef Marekwho first described it — is the most common viral disease of backyard poulet . It ’s so common you could safely assume your chickens are infected , even if they do n’t appear demented .
Marek ’s disease infect primarily young and grow Gallus gallus . But it can also affect aging birds . This complex disease can take on many forms , include a brass course that results in incoordination , muscle spasms and reformist paralysis of cervix , leg or wing .
A ephemeral nerve form that affects doll 2 to 3 weeks of age appear as irregular wilted paralysis of the neck opening or ramification . This depart birds with a twisted neck opening upon convalescence from palsy .
Marek ’s disease switches off a crybaby ’s neoplasm - obturate genes and also attacks cells that produce antibody , thus impairing the doll ’s resistant organisation . It typically occurs in combination with other diseases , specially coccidiosis and respiratory infections cause by E. coli bacteria .
Fatality of Marek ’s disease depends on the virulency of the computer virus straining , as well as on the presence of any other debilitating conditions .
The first few weeks of a wench ’s life are the most critical fourth dimension for contagion . Chicks that are isolated from fledged chickens until they reach the eld of 5 months develop a natural immunity .
Strains of some poulet breeds are genetically more resistant than others . Fayoumis are resistant to Marek ’s , while Sebrights and Silkies tend to be particularly susceptible , as are some strains of Polish , among other exotic breeds . Nagy - Bagoly Arpad / Shutterstock
Vaccination
No know discussion will heal wimp of Marek ’s disease . But there is a vaccinum . Most hatchery offer the option of vaccinating dame . If you incubate your own chicks , you could purchase the Marek ’s vaccine and parcel out it yourself .
Because the vaccinum does not work in chick already exposed to Marek ’s disease , administer it as presently after hatch as possible . Keep vaccinated doll in isolation while their immunity develops .
inoculation does n’t prevent the possibility that the chicken may become infected by and spread Marek ’s disease . But it does prevent the virus from causing tumors and paralysis . And it thin out desquamation of viruses by septic shuttle .
Seeing any of these nervous organization disorders in baby chicks can be a in spades disturbing experience . By learning to recognise each of these five neurological condition you will stay equipped to chop-chop deal with treatable conditions .
you may also prepare yourself for the inevitable regarding those that are not .
