Addled: an egg where the contents are decomposing.
Air cell: the air space usually found at the large or blunt end of an egg.
Albumen: the white of an egg.
Amino acids: the simpler building units of protein.
Anticoccidial: a anticoccidial drug used to treat or prevent coccidiosis
Artificial insemenation: the introduction of semen into the female oviduct by methods other than by natural mating.
Aviary system: a system of housing based on the litter system where a number of mezzanine floors are installed to increase the available floor space and, in so doing, provide the space for more birds in the poultry house.
Beak trimming: The removal of part of the beak of poultry by specially designed equipment to prevent cannibalism and its associated vices.
Blastoderm: the fertilised nucleus of the egg from which the chicken develops.
Blastodisc: The unfertilised nucleus of an egg. No chicken can develop from a blastodisc.
Breed: a group of birds that reproduce their own likeness in their offspring. A variety is a group within a breed that are distinguished by a difference of a single characteristic eg. feather colour or comb type.
Broiler: a young bird of either sex bred and grown specifically for highly efficient meat production. Broilers are usually killed at 5 to 7 weeks of age (alternative term - meat chicken).
Brooder: the equipment used to provide supplementary warmth during the early stages of the chickens life. The energy used may come from electricity, gas, oil or from other sources.
Brooding: the period of the first weeks of a chickens life when it requires a very high standard of care including the provision of special diets and supplementary warmth.
Broody: the instinct controlled by maternal hormones that causes the female to want to set on eggs for hatching and to care for the chickens that hatch.
Caeca: the two blind gut of the digestive tract attached to the distal end of the small intestine.
Cages: a system of housing where the birds are confined to a wire floor singly or in multiples. With this system the stock do not come into contact with their own or other birds faeces - an important disease control measure.
Candle: to assess some internal characteristics of the egg by viewing it in a darkened room with a bright light behind the egg.
Cannibalism: the practice by some birds of attacking and eating other members of the same flock.
Chalazae: a type of albumen that surrounds the yolk of the egg and extends as creamy white, twisted, ropelike structures into each end to anchor the yolk in the centre of the egg.
Chick: the term used to describe chickens from day old to the end of brooding.
Chick-type drinker: a drinker that is more suitable for young chickens to access water.
Chick-type feeder: a feeder that is more suitable for young chickens to access food.
Clear eggs: infertile eggs (containing no embryos) usually removed from the incubator during incubation.
Cloaca: the common external opening for the digestive, urinary and reproductive tracts of the fowl.
Coccidiostat: a drug usually added to the food and used to prevent the disease coccidiosis.
Cock: a male that has finished one seasons as a breeder. Usually refers to older birds.
Cockerel: a young male from day old to the end of its first year of breeding. Often used to refer to young males up to 6 months of age.
Controlled environment housing: an intensive housing system where the operator can control temperature, air quality and light.
Crop: an organ, a part of the esophagus, located at the base of the neck and used as a storage place for food after eating but before digestion.
Crossbred: a bird with parents of two or more different genotypes (or breeds or varieties).
Crude protein: the nitrogen sources in food. It is not true protein as nitrogen is found in dietary compounds other than protein.
Cull: the identification and removal of non-productive birds from the flock.
Cuticle: the outer membrane or bloom on the eggs shell.

Hen housed average: progressive egg production record calculated on the basis of the number of birds placed in the laying house at point of lay.
Hock: the joint of the leg between the lower thigh and the shank. It is most commonly the region where the feathered portion of the leg ends and the scaly shank of the lower leg starts.
Hover: a canopy used on brooders to direct the heat downwards to the chickens.
Incubation: the process by which fertile eggs are subjected to conditions suitable for the initiation and sustaining of embryonic development and the hatching of strong, healthy chickens.
Incubator: the machine used to incubate fertile eggs.
Insoluble grit: hard, insoluble material such as granite, flint or bluestone chips consumed by the birds to aid in the grinding of the food in the gizzard.
Intensive system: any system of housing poultry where the birds are indoors all of the time and do not have access to the outside. It usually entails higher stocking densities.

Keel: the breastbone or sternum of the fowl. This bone has a large surface area to provide for the attachment of the large muscles of flight (the breast muscles).
Layer: a female in lay. Usually used to refer to females kept solely for egg production for human consumption.
Layer cycle: the period from the onset of lay until the natural moult causes a cessation of production. Usually used to describe the period during which an economic level of production is being maintained.
Lighting (artificial): the use of controlled artificial light to regulate the day length under which the stock are kept.
Livability: the expression used to describe the number of survivors in a flock:
Lux: a unit of illumination equal to one lumen per square metre. Used to measure the brightness or intensity of light.

Lots of poultry terms on the Ultimatefowl Poultry wikipedia one could probably copy off as well. Not to mention various books you can find online.
God bless,

Meat chicken: see broiler.
Metabolisable energy (ME): the energy in a food ingredient or diet available for metabolism (use by the animal for normal body functions and activity).
Metabolism: the sum of the chemical changes in living cells which provide energy for the vital activities and processes of the body.
Methionine: one of the essential amino acids.
Micro-ingredient: an essential ingredient in the diet that is required by the bird in very small quantities.
Moult: the process whereby the bird sheds its feathers and ceases egg production. It is usually initiated by hormonal influences but is often triggered by stress.
