Turkeys and chickens are susceptible to many of the same diseases, including cholera, influenza, and various bacterial and viral infections. However, there are some key differences in the types of infections that affect these two types of poultry. For example, turkeys are more vulnerable to blackhead infections than chickens, and the most common cause of lameness in turkeys is Mycoplasma infection, which can be transmitted through the air, the egg, and mating. Chickens, on the other hand, are more commonly affected by Marek's disease, a type of avian cancer, and lymphoid leukosis, which can also infect turkeys but on a smaller scale. Additionally, wild turkeys that live near human populations are at risk of disease transmission from backyard chickens, and chickens themselves can be carriers of certain diseases, such as avian influenza, without showing any symptoms. While it is difficult to make a definitive statement on whether turkeys are more prone to feather infections specifically, the available literature suggests that both turkeys and chickens face significant health risks and that the impact of these infections can vary between the two species.

Turkeys are more prone to blackhead infections than chickens
Turkeys are highly susceptible to blackhead disease, with mortality rates ranging from 70 to 100% in infected flocks. In contrast, the disease is less severe in chickens, although it can still lead to poor health and reduced egg production. The reason for the higher susceptibility of turkeys is not entirely clear, but it may be due to the fact that chickens can be infected carriers for a long time without showing severe symptoms or dying. This allows them to continue spreading the disease to other birds.
The symptoms of blackhead disease include lethargy, reduced appetite, poor growth, increased thirst, sulphur-yellow diarrhea, and dry, ruffled feathers. The head of the infected bird may also become cyanotic, turning bluish in colour, which gives the disease its common name, blackhead.
Prevention of blackhead disease in turkeys focuses on two main strategies: preventing exposure by quarantining infected birds and avoiding contact with chickens or other game birds, and using migration barriers to prevent infected and uninfected birds from commingling. Deworming of birds with anthelmintics can also reduce exposure to the cecal nematodes that carry the protozoan. While there are no highly effective treatment drugs for blackhead, research is ongoing to develop new treatments and improve control measures.

Feather infections in chickens and turkeys can be caused by the same viruses
Chickens and turkeys are susceptible to many of the same diseases, which can cause feather infections. These diseases can be caused by bacteria, viruses, or parasites.
One such disease is pullorum, which affects chickens and turkeys and is caused by the Salmonella gallinarum bacterium. It spreads through egg transmission and mechanical transmission, and birds of any age can be infected, though it primarily affects young adults. Symptoms include listlessness, green or yellow diarrhoea, and ruffled feathers.
Another disease that affects both chickens and turkeys is Marek's disease, a type of avian cancer caused by a virus. Tumours can occur in the eyes, causing irregularly shaped pupils and blindness, and in the liver, kidney, spleen, gonads, pancreas, proventriculus, lungs, muscles, and skin, causing enlarged feather follicles.
Avian influenza, caused by a virus of the Orthomyxoviridae family, is one of the most devastating diseases in chickens and turkeys, though it can also infect other birds. Infection is caused by contact with the faeces of sick birds and by secretions from their eyes and nostrils.
Infectious laryngotracheitis is another virus that affects chickens and turkeys, causing respiratory symptoms and potentially leading to suffocation.
Additionally, chickens and turkeys can both be affected by ulcerative enteritis, caused by the bacterium Clostridium colinum, which spreads through the droppings of sick or carrier birds. Birds with the acute form of the disease may die suddenly, while those with the chronic form become listless, have ruffled feathers, and develop a humped-up posture.
While these diseases can affect both chickens and turkeys, it is important to note that some may have a higher prevalence or severity in one species compared to the other. For example, blackhead, caused by the parasite Histomonas Meleagridis, affects both chickens and turkeys but turkeys are more vulnerable to infection. Similarly, the Mycoplasma infection, which can cause respiratory disease and lameness, is the most common cause of lameness in turkeys, but it also affects chickens.

Chickens and turkeys can transmit diseases to each other
Another disease that affects both chickens and turkeys is pullorum, which is often fatal to young birds. It can be transmitted through the egg, and infection usually occurs while the birds are still in the hatchery.
Chickens and turkeys can also transmit Marek's disease to one another. Marek's disease is a type of avian cancer that causes tumours in nerves, leading to lameness and paralysis. The virus is transmitted through the air within poultry houses. Lymphoid leukosis is another type of avian cancer that primarily affects chickens but can also infect turkeys.
Both chickens and turkeys can contract fowl cholera, which usually affects birds older than six weeks. It can cause fever, reduced feed consumption, mucoid discharge from the mouth, ruffled feathers, diarrhoea, and laboured breathing.
In addition, chickens and turkeys can transmit infectious laryngotracheitis to each other. This disease is caused by the presence of the ILT virus and results in respiratory symptoms.
Furthermore, chickens and turkeys that live in close proximity to one another can increase the risk of disease transmission, especially in wild turkeys that come into contact with backyard chickens. This can lead to the spread of illnesses such as blackhead, caused by a parasite that turkeys can ingest through contaminated soil.
To prevent the transmission of diseases between chickens and turkeys, it is important to maintain proper hygiene and biosecurity measures, such as isolating poultry from other birds and cleaning equipment regularly.

Turkeys are more prone to bacterial feather infections than chickens
Firstly, turkeys are more susceptible to bacterial infections because they are larger and require more space than chickens. In addition, they need more hands-on care when they are young and cannot fend for themselves as readily as chicken chicks. This means that any bacteria in their housing or bedding material are more likely to be transmitted to the birds. Poor housing conditions, such as dirty or damp bedding, can also lead to a higher risk of bacterial infections in turkeys.
Secondly, turkeys are more vulnerable to certain bacterial infections that are transmitted by other birds, such as chickens. For example, blackhead, caused by the Histomonas Meleagridis parasite, is carried by the caecal worm, which can live in the guts of chickens. When turkeys come into contact with infected chicken droppings, they can ingest the worm eggs, leading to a severe infection that causes inflammation, diarrhoea, and often death. This is a particular issue when chickens and turkeys are kept together or on the same ground, as is often the case in backyard flocks.
Furthermore, turkeys have different immune responses to chickens, which can make them more susceptible to certain bacterial infections. For example, the Mycoplasma bacterium, which causes respiratory disease and swollen leg joints, is a common problem in turkeys and can be transmitted through the air, eggs, or mating. While chickens can also be infected with Mycoplasma, it is less likely to cause disease in mature birds.
In addition to these factors, the close proximity of turkeys to human populations and the increasing popularity of backyard chicken flocks have led to a higher risk of disease transmission between domestic poultry and wild turkeys. This includes bacterial infections such as avian influenza, which can be transmitted through the faeces of sick birds.
Overall, while both chickens and turkeys are susceptible to bacterial feather infections, turkeys may be more prone to these infections due to their size, housing conditions, immune responses, and exposure to other infected birds.

Chickens and turkeys can be vaccinated to prevent feather infections
Chickens and turkeys are susceptible to a variety of diseases, some of which can be prevented through vaccination. While chickens are more prone to feather infections than turkeys, both birds can suffer from feather infections caused by various pathogens.
Marek's disease, caused by a virus, can lead to tumors in nerves, eyes, and various organs, resulting in lameness, paralysis, blindness, and enlarged feather follicles. Vaccination at hatcheries or by individual owners is crucial to establishing early immunity in chickens. The virus is transmitted via feather dander, making early vaccination essential.
Infectious bronchitis, caused by a gammacorona virus, results in respiratory issues, nephritis, decreased egg production, poor growth, and high morbidity. Commercial poultry are routinely vaccinated against this virus due to its economic significance.
Fowl cholera, which affects turkeys and chickens, causes fever, reduced feed consumption, mucoid discharge, ruffled feathers, diarrhea, and labored breathing. A vaccine is available for use in endemic areas or farms.
Lymphoid leukosis primarily affects chickens but can also infect turkeys and other birds. It causes progressive emaciation, regression of the comb, and greenish diarrhea. Vaccination at hatcheries can prevent tumor formation, but it does not prevent infection.
Additionally, blackhead, caused by a parasite, affects turkeys more severely than chickens. It leads to inflammation, diarrhea, and severe liver damage. While there is no mention of a vaccine, oregano (Viovit) is used to reduce the chances of infection.
Other diseases that affect chickens and turkeys include pullorum disease, salmonella, ulcerative enteritis, and respiratory diseases. While some of these diseases may not have specific vaccines mentioned, ongoing research is focused on developing effective immunization strategies, including recombinantly constructed vector vaccines and modified live virus vaccines.
