Some parts of the face are shrunken, eyes might be partly open or they look dull, nostrils are crusted and caked. The signs of poultry disease in musculature are loss of strength and weight, muscles near crop cavity and keel are shrunken which results in animal having a less think breast. Other than this the signs of poultry diseases in legs and feet are prominent tendons with dehydration, enlargement of joints and they get warm when they are touched.

The poultry diseases or infections in animals or birds can be caused by various means such as other local poultry which includes ducks, chickens, turkeys, geese, and guinea fowl. And even live birds or dead poultry that are not properly disposed of. Other sources of poultry diseases include wild birds, animals, other local livestock, humans, snails, earthworms and slugs, arthropods including mites, fleas, mosquitoes, and lice. At times the insects that can be eaten by poultry can also cause poultry diseases. Inanimate sources of poultry diseases are food eaten by poultry that may have bacteria, toxins or fungi. One of the sources of poultry disease is water which is essential and its supply should be clean. Dirty, stagnant water that has organic waste may contain large amount of protozoa, bacteria or fungi. Dust, soil and litter may have spore containing organisms such as bacteria, fungi that can invade in an animal's body by a wound. Structures such as houses that are in use for poultry may not be kept clean or they are not properly ventilated. This can also cause to poultry diseases.

Vectors are organisms that carry disease causing organisms called parasites in their bodies to infect other organisms called hosts. For e.g. mosquitoes which are vectors and their parasite is malaria. Parasite grows and multiplies in the body of a vector. Bacterial diseases which are a category of poultry diseases have many types such as salmonella which can occur at any age but it's mainly in chicks, Mycoplasma which can occur at any age. Then there are fungal diseases which is also a category of poultry diseases, it includes aspergilloses which is mostly found in chicks, mycotoxicoses it can occur any age in animals. And there is a type of poultry disease which is parasitic; it has further types too such as coccidiosis.
