Viral diseases

- Avian infectious bronchitis, caused by a strain of Avian coronavirus previously known as infectious bronchitis virus[2]
 - Avian infectious laryngotracheitis, caused by Gallid alphaherpesvirus 1[3]
 - Avian influenza, caused by Avian influenza virus[4]
 - Duck plague, caused by Anatid alphaherpesvirus 1
 - Chicken infectious anemia, caused by Chicken anaemia virus[5]
 - Epidemic tremor, caused by Tremovirus[6]
 - Fowlpox, caused by viruses in the genus Avipoxvirus
 - Infectious bursal disease (IBD), also known Gumboro disease, caused by Infectious bursal disease virus
 - Lymphoid leukosis caused by avian sarcoma leukosis virus
 - Marek's disease
 - Newcastle disease
 - Viral arthritis, caused by Avian reovirus[7]
 
Parasitic diseases

Infestation of Echidnophaga gillinacea fleas on the comb and around the eye of a chicken
- Scaly leg, caused by the mite Knemidocoptes mutans[8]
 - Infestation by Dermanyssus gallinae, the red poultry mite[9]
 - Infestation by Echidnophaga gallinacea, the sticktight flea[10]

Protozoal diseases
- Histomoniasis (blackhead disease), caused by Histomonas meleagridis
 - Coccidiosis
