Chicken Glasses , also known as chicken specs , chicken glasses , generally as election guard and under other names, are small sunglasses made for chickens intended to prevent puncturing feathers and cannibalism. They are different from the blind because they allow the bird to look forward while the blinders do not. One variety uses a rose-colored lens because the staining is thought to prevent chickens from using it to recognize blood in other chickens that can increase the tendency for abnormal abnormal behavior. They are mass-produced and sold throughout the United States as early as the 20th century.

Description and destination
Chicken glasses are often made of celluloid or aluminum and usually consist of "two oval panels that fit above the beak of the chicken's beak, a pin is inserted through the nostrils to hold the oval pieces in place." Different designs are produced that are attached to the chicken head in different ways. Some are held in place by rope, some by small hooks to nares (nostrils) and some with piercing bone of the septum between the nostrils with the cotter pins. Due to network piercing, this last type of design is illegal in some countries.
Some versions of the device have semi or fully transparent lenses while others are colored, often red or rose. Another design is an opaque blindfold and completely prevents future vision. The intended purpose of the chicken eyewear is to prevent aggressive pecking, cannibalism and pecking feathers.
Chicken eyewear is an alternative to the half-trimming, which is the removal of about a third of the beak with a cold or hot knife, or infrared light, usually when the chick is 1 day old. It is often effective in reducing pecking injuries, but causes pain and has a significant effect on chicken welfare.
Red lenses
Red-colored lenses are considered effective in reducing pecking internecine because they disguise the color of blood. As summarized in a 1953 article in the Indiana National Road Traveler newspaper, "The deep rose-colored plastic lens makes it impossible for the cannibal [chicken] to see blood on other chickens, although it is possible to see the grain in soil. "
Elmer Haas from National Band & amp; The Tag Company, the main producer of rose-colored rose eyeglasses, whose grandfather "designed the wire frame for chickens in 1902," indicates that he believes that the effect of blood dye disguises is a myth: "the company adds colored rose roses for pampering chicken owners... [ c] blind colored hickens ". (In fact, chickens, like other birds, have good color vision.) The company has added a feature of rose color to his glasses in 1939 under the brand name "Anti-Pix". These sunglasses are more complicated than others because red lenses are fitted to the hinges at the top of the frame. This means that when the mother hen bows her head to feed, the lens is swung out giving the chicken an unobstructed view of the ground. When a hen raised her head, just as she would during aggression, the lens would swing down to give the red perception bird to the environment.
Red contact lenses, rather than glasses, have also been proposed to reduce cannibalism in chickens.

History
A form of chick eyewear was first patented in 1903 by Andrew Jackson Jr. from Munich, Tennessee, as "Eye-protectors for chickens". In the US, they are available through Sears-Roebuck's ordering company, or through a chicken feed store for a few cents. Glasses are no longer produced by National Band & amp; Corporate Tags, but sought as collector's goods.
Using chick eyeglasses was still practiced in 1973, as evidenced by a report in The Hawk-Eye Illinois newspaper that a farmer had 8,000 chickens equipped with rose varieties. One of the inventors of the proposed eyewear form of legislation in Kansas to require all chickens in the state to be equipped with eyeglasses, but his campaign was unsuccessful.
In popular culture
On January 16, 1955, Sam Nadler of the Brooklyn National Agricultural Equipment Company appeared on CBS's popular primetime television show, What is My Line? The show is in a guessing game format, in which the panel tries to determine the contestant's line (work). Shows an official who mentions Mr. Nadler to the audience as "selling 'glasses' for chicken". After the panel did not succeed in guessing his work, Mr. Nadler was revealed and he stated that his company sells 2-3 million pairs of chicken glasses per year. What's My Line? ' s director, Frank Heller, said in 1958 that "the most unusual occupation" on the show for eight seasons was "... the guy who made the glasses for the chicken."
