Domestic Poultry Honor

Nature Study

Requirements

  1. Identify, through photographs or in real life, at least 5 breeds of chickens, such as for example:
    • Plymouth (of any color)
    • Wyandotte (of any color)
    • Rhode Island Red
    • Orpington (of any color)
    • Leghorn (of any color)
    • Indian Giant
    • Turken

    Answer: 1) Plymouth Rock (in any color): the best-known variety is the Barred (feathers striped in black and white bars); an American dual-purpose breed (meat and eggs), medium-large build and docile temperament. 2) Wyandotte (in any color): feathers with a laced pattern, a rounded and compact body, a rose-type comb; an American dual-purpose breed, a layer of brown eggs. 3) Rhode Island Red: dark reddish-brown feathers, a rectangular body; an American breed of excellent laying ability, one of the best brown-egg layers. 4) Orpington (in any color): abundant and soft feathers (common in buff/yellow and black colors), a large, heavy, and very docile bird; an English dual-purpose breed. 5) Leghorn (in any color): the most common is the white one, a slender and light bird, with a large comb; an Italian breed, an excellent white-egg layer, the basis of commercial laying hens. 6) Indio Gigante: a large-sized and quite tall bird, of Brazilian origin, raised mainly for meat and for show. 7) Turken (Naked Neck): characterized by a featherless neck (a "turkey" appearance), a rustic and heat-resistant breed, dual-purpose. — The identification of breeds is based on weight, conformation, plumage, egg color, and purpose. Plymouth Rock and Wyandotte are American dual-purpose breeds. The Rhode Island Red was the basis of commercial laying until the 20th century. The Orpington is English, docile, great for home-raising. The Leghorn (Italian, a light breed) dominates the commercial white-egg layer market, with up to 300 eggs/year. The Indio Gigante is a Brazilian meat breed bred up for size. The Turken/Naked Neck has a genetic absence of feathers on the neck — it is not a cross with a turkey, despite the name.

  2. For each of the chosen chickens, describe the following:
    • Origin
    • Physical characteristics (weight, height, feather color)
    • Purpose (layers, ornamental, etc.)

    Answer: 1) Origin: indicate the country and the year (or period) in which the breed was developed/recognized. Examples: Leghorn — Italy; Orpington — England; Plymouth Rock, Wyandotte, and Rhode Island — United States; Indio Gigante — Brazil. 2) Physical characteristics (weight, height, feather color): provide the average weight of the male and female, the build/height of the bird, the color and pattern of the feathers, the type of comb, and the color of the egg. E.g.: the Leghorn is light (about 2 to 2.7 kg), with white feathers and a large comb; the Orpington is heavy (3.5 to 4.5 kg), with abundant yellow or black feathers. 3) Purpose: classify what the breed is raised for — laying (egg laying), meat (meat production), dual-purpose (meat and eggs), or ornamental/show. E.g.: the Leghorn is a white-egg layer; the Orpington is dual-purpose and very docile; the Indio Gigante is a meat and ornamental breed. — The description follows the standard used in poultry-farming books (APA, ABNAB). Origin points to the country and context of development (England, USA, Italy, Brazil). Physical characteristics: weight (rooster/hen), build, plumage, comb (single, pea, rose), skin and egg color. Purpose classifies the economic function: layer (Leghorn, Rhode Island), meat (Cornish, Indio Gigante), dual-purpose (Plymouth, Orpington), ornamental (Sebright, Polish). This standard allows a technical evaluation of the breeds observed by the Pathfinder.

  3. Identify, through photographs or in real life, 2 breeds of each of the following birds:
    • Duck
    • Teal
    • Goose
    • Turkey
    • Quail

    Answer: 1) Duck: two breeds, for example the Pekin (white, large, raised for meat) and the Wild Duck/Mallard (the male with a bright green head, smaller and more rustic). 2) Mallard duck: two breeds, for example the Pekin (white and heavy) and the Indian Runner (an upright body when standing, excellent egg laying). 3) Goose: two breeds, for example the Toulouse (gray plumage, a large and heavy bird) and the Embden (white, large, with an orange beak and legs). 4) Turkey: two breeds, for example the Common Bronze (dark feathers with a bronze-colored sheen) and the Broad Breasted White (white, a commercial meat line). 5) Quail: two breeds, for example the Japanese/Coturnix (raised for egg laying) and the Bobwhite/American (a game quail, more rustic). — The requirement specifically asks for the identification of two breeds for each of the five domestic birds listed. The observation can be in real life or through images. For example, the mallard is one of the best-known duck breeds.

  4. Demonstrate how to find out whether an egg is fertilized.

    Answer: By candling: in a dark room, with a powerful flashlight behind the egg, between the 7th and 10th day of incubation. A fertilized egg shows a network of blood vessels radiating from a central point. An unfertilized one stays translucent, with only the shadow of the yolk. In a raw egg opened up, the fertilized germinal disc has a ring shape (the blastoderm). — Candling is the standard technique used by poultry farmers. The flashlight (preferably white LED, narrow beam) reveals embryonic development from the 5th day. At 7-10 days, blood vessels form a spider-web pattern. Clear (translucent) eggs are infertile and can be discarded. In raw eggs, the fertilized germinal disc (blastodisc) has the appearance of a small double ring, while unfertilized ones are just an opaque spot. Candling avoids wasting space and energy in incubators.

  5. What is the average incubation period of the eggs of the following birds:
    • Quail
    • Guinea fowl
    • Chicken
    • Duck
    • Teal
    • Turkey

    Answer: 1) Quail: 17 to 18 days. 2) Guineafowl: 26 to 28 days. 3) Chicken: 21 days. 4) Duck: 28 days (domestic lines; the Muscovy/Cairina can reach 35 days). 5) Mallard duck: 28 days. 6) Turkey: 28 days. Small variations of 1 to 2 days can occur depending on the temperature and humidity of the incubator or natural nest, but these average values are the ones accepted as the standard in poultry farming. — The periods were established by historical observation recorded in poultry farming. Quail (Coturnix japonica) have the shortest cycle (17-18 days), which is why they are preferred in commercial production. Chickens (Gallus gallus domesticus) have a standard of 21 days. Common ducks (Anas platyrhynchos) and mallard ducks take 28 days; the Muscovy duck (Cairina moschata), on the other hand, reaches 35 days, an exception. Guineafowl (Numida meleagris) and turkey (Meleagris gallopavo) are also around 28 days. Ideal temperature: 37.5°C; humidity 50-60%.

  6. What is cockfighting? What are the legal implications of getting involved with this type of activity?

    Answer: Cockfighting is the forced fighting of roosters for betting, considered a crime of animal cruelty under art. 32 of Law 9.605/98 (Environmental Crimes). The penalty is detention of 3 months to 1 year and a fine, which can be doubled if the animal dies. Promoters, organizers, breeders, and bettors are criminally liable, with the seizure of the birds and of the goods used. — Cockfighting is a criminal tradition recorded in various regions of Brazil, with crossbred (fighting) roosters that are fitted with metal spurs and given drugs to fight to the death. The STF (Supreme Court) declared unconstitutional state laws that tried to authorize it (ADI 2514). Joint operations involve the Civil Police, the Environmental Police, and the Public Prosecutor's Office. In addition to Law 9.605/98, the Constitution (art. 225, §1, VII) prohibits practices that subject animals to cruelty. There is also a risk for bettors: criminal classification as illegal gambling (jogo do bicho).

  7. Complete one of the following and present a report of at least 1 page:
    • Care for a domestic fowl for at least 6 months.
    • Follow the incubation process (natural or artificial) of a clutch of eggs until hatching.
    • Visit a poultry farm and observe the care routines (feeding, vaccination, etc.) of the birds.

    Answer: Fulfill one of these three options: (a) take care of a domestic bird for 6 months, recording feeding and management; (b) follow the natural or artificial incubation of a clutch until hatching; or (c) visit a poultry farm observing feeding and vaccination routines, with a final report of at least 1 page. — Each of the three options develops a different skill. Caring for 6 months teaches daily management, feed cost, observation of diseases. Following incubation covers the biology of embryonic development, with thermometers, candling, humidity control. A technical visit exposes the industrial scale: vaccination against Newcastle, Gumboro, Marek; rations balanced by phase; biosecurity. The 1-page report forces written synthesis and fixes the learning in a consultable record.
