One of the most common upper respiratory infections that plagues chickens, mycoplasma is a bacterial disease that causes chronic respiratory disease in chickens.
Symptoms of mycoplasma include:
- Sneezing
- Nasal discharge
- Breathing difficulties
Treatments may include antibiotics, and preventive measures include purchasing birds from certified disease-free sources.
Other Chicken Ailments to Watch For
In addition to the major viral and bacterial diseases, several other health issues can affect the quality of life and productivity of backyard chickens. Recognizing these can help in early intervention and treatment.
11. Impacted Crop
The crop is a muscular bag located at the bottom of a chicken’s neck. Feed is stored in the crop, and it contains enzymes that break the feed down before it’s digested. Unfortunately, the crop can become impacted when chickens eat materials that cannot be digested easily.
Symptoms of an impacted crop include:
- A swollen crop
- Regurgitation
Treatment involves massaging the crop and providing olive oil to help pass the obstruction. Preventative measures include ensuring access to grit and avoiding long, tough grasses in your chickens’ diet.

12. Parasites
Chickens can be affected by mites, flies, worms, lice, ticks, and other parasites. These organisms are both uncomfortable for your feathered friends and they can cause health issues like anemia, tissue damage, and infection.
Symptoms of mites, lice and ticks include:
- Itching
- Feather loss
- General discomfort
Treatments for parasites in chickens include natural dusting powders and prescribed medications, while maintaining clean and dry chicken coop bedding material is crucial for prevention.
Here are a couple of other common parasites to watch out for.
Red Mites
Red mites are a common problem among backyard chicken owners. These nasty little bugs typically infest the crevices of the coop itself and feed on chickens at night. They can cause severe discomfort for your flock, leading to symptoms such as restlessness, decreased egg production, and pale combs.
If you suspect red mites are a problem for your hens, look for signs of increased nighttime restlessness. Also, check the coop for tiny red or black spots, especially in crevices and on perches. Observe if your chickens are exhibiting decreased egg production or appear anemic with pale combs and wattles.
Flystrike
Flystrike is another painful and potentially deadly parasite to watch for, which occurs when the blowfly lays eggs in the skin of a chicken’s vent.
Symptoms of flystrike include visible eggs, larvae, or insect movement in and around the vent, as well as bleeding or dead tissue around the vent area.
13. Chicken Obesity
Obesity in chickens can lead to several health issues, including decreased egg production and increased susceptibility to disease. Symptoms include excessive body weight and difficulty moving. Managing diet and ensuring adequate exercise are key preventative measures.

14. Rickets
Caused by a deficiency of vitamin D, calcium, or phosphorus, rickets leads to weak and malformed bones in chickens. Symptoms of rickets include bowed legs and frail bones.
Providing a balanced diet with adequate nutrients is essential for prevention and treatment of rickets.
15. Botulism
You may have heard about botulism in your studies of canning practices. However, this potentially fatal poisoning can also occur in chickens when birds ingest the toxin-producing bacteria. This can be deadly since the toxin paralyzes the breathing muscles.
Symptoms of botulism include:
- Weakness
- Flaccid paralysis
- Death
There is no treatment that’s specific to botulism, and if your birds eat too much of the bacteria, they will likely die. If only a small amount is consumed, however, they may be able to recover. Separate the bird from the rest of the flock and provide access to clean feed and water.
Preventing access to decomposing organic material is vital for prevention of botulism.
16. Thrush
Thrush is a fungal infection that affects the digestive tract of chickens. Symptoms of thrush include white lesions in the mouth and throat.
Antifungal treatments and maintaining good coop hygiene can help manage and prevent this condition.
17. Frostbite
Chickens are susceptible to frostbite during cold weather, particularly on their combs and wattles. Symptoms of frostbite include discoloration and blisters.
Providing a well-insulated and well-ventilated coop that’s free from drafts and damp conditions is the best way to keep chickens warm in winter months.
18. Physical Wounds or Trauma
Physical injuries can occur from predator attacks or pecking among the flock. You can spot a wounded chicken with regular bodily inspection and by watching for damaged skin, blood on feathers, or bruising.
Immediate cleaning and dressing of wounds, along with proper flock management, are necessary to prevent infection and other complications.
19. Foot Injuries
Foot injuries can occur from improper perch design or debris in the coop. Symptoms include limping or reluctance to walk. Providing safe and clean perching spaces is essential for prevention.
20. Fungal Diseases
Fungal diseases can affect the respiratory system or skin of chickens. Symptoms include respiratory distress and skin lesions. Keeping the coop dry and clean is crucial for prevention.
How to Prevent Common Chicken Diseases and Ailments
Preventing diseases in chickens involves more than just reacting to symptoms when they pop up. It requires proactive management of their living environment before symptoms have a chance to present.
Regular cleaning of the chicken coop, ensuring fresh water and food daily, and providing a spacious, safe outdoor area are all fundamental to disease prevention in your backyard flock.
Vaccinations and regular health check-ups can also dramatically reduce the incidence of many common chicken diseases and ailments.
