Ornamental Chickens|10 Common Diseases (cause → signs → examination → treatment direction → prevention)
Ten common diseases of ornamental chickens (including bantams) gathered into one table: Newcastle disease, avian influenza, coccidiosis, salmonellosis, dermatophytosis/feather mites, external parasites (red mite/poultry lice), colibacillosis, respiratory infection, traumatic injury (rank conflict in mixed flocks), and egg-related disorders (egg binding and others). Each row lists cause, signs, examination, treatment direction and prevention; the treatment column gives categories only, never doses. It suits checking against when something looks wrong and you need to narrow down the direction first, or when taking on new birds.
This content is compiled from the disease table for ornamental chickens (including bantams) in the backyard poultry chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.
| # | Disease (Chinese/English) | Cause | Signs | Examination | Treatment direction | Prevention |
|---|---|---|---|---|---|---|
| 1 | Newcastle disease | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group |
| 2 | Avian influenza | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | This falls under statutory reporting and stamping-out measures | Same as the laying hen group |
| 3 | Coccidiosis | Same as the laying hen group; in small-bodied birds the disease may worsen faster | Bloody droppings, diarrhoea, dullness | Faecal microscopy | Antiparasitic medication must be prescribed; assess at emergency level | Keeping litter dry |
| 4 | Salmonellosis | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Antibiotics must be prescribed, and a withdrawal period comes into play | Same as the laying hen group |
| 5 | Dermatophytosis / feather mites | In long-plumed breeds such as the Silkie the feathers dry slowly, so in a damp environment the risk of skin fungus and feather mites is higher than in ordinary short-feathered breeds | Redness and swelling of the skin, poorer feather quality, scratching behaviour | Skin-scraping microscopy | Antifungal/antiparasitic medication must be prescribed | Damp-proofing the coop, checking feathers and skin regularly |
| 6 | External parasites (red mite/poultry lice) | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group |
| 7 | Colibacillosis | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group |
| 8 | Respiratory infection | Poor environmental hygiene, stress, overcrowded group housing | Abnormal breathing sounds, increased discharge | Auscultation, swab testing | Antibiotics must be prescribed | Managing ventilation |
| 9 | Traumatic injury (rank conflict in mixed flocks) | When bantams are kept with large breeds their smaller size puts them at higher risk of being pecked | Wounds and bleeding, feather loss | Visual inspection | Wound care needs veterinary assessment | Assessing compatibility for group housing, separating into areas where necessary |
| 10 | Egg-related disorders (egg binding and others) | Same as the laying hen group | Same as the laying hen group | Same as the laying hen group | An emergency; seek care immediately | Same as the laying hen group |

Limits of this content
This content comes from the backyard poultry chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
