Chicken eyeglasses
Chicken eyeglasses, also known as chicken specs, chicken goggles, generically as pick guards, and under other names,
Description and purpose
Chicken eyeglasses were often made from celluloid or aluminum
Some versions of the devices had lenses that were semi- or fully transparent whereas others were tinted, often red- or rose-colored. Other designs were blinders which are opaque and completely prevent forward vision.[2][7] The intended purposes of chicken eyeglasses were to prevent aggressive pecking, cannibalism, and feather pecking.
Chicken eyeglasses are an alternative to beak trimming, which is the removal of approximately one-third of the beak by a cold or heated blade, or an infrared beam, usually when chicks are one day old. This is often effective in reducing pecking injuries, but causes pain and has significant effects on chicken welfare.[7][8][9][10][11]
Red-tinted lenses
Red-tinted lenses were considered to be effective in reducing internecine pecking because they disguise the color of blood.[7] As summed up in a 1953 article in Indiana's National Road Traveler newspaper, "The deep rose-colored plastic lenses make it impossible for the cannibal [chicken] to see blood on the other chickens, although permitting it to see the grain on the ground."[12]
Elmer Haas of the National Band & Tag Company, a major producer of rose-colored chicken eyeglasses, whose grandfather had devised wire frames for chickens in 1902,[13] indicated that he believed the purported blood-masking effect of the rose coloring was a myth: "the firm added the rose colored glasses because it indulged the chicken owners ... [c]hickens are color blind".[13] (In fact, chickens, like other birds, have good color vision.[14]) The firm had added the rose-colored feature to its glasses in 1939 under the brand name "Anti-Pix".[15] This variety of eyeglasses was more complicated than others because the red lenses were fixed to a hinge at the top of the frame. This meant that as the hen lowered its head to feed, the lens swung out giving the hen an unobstructed view of the ground. When the hen raised her head, as she would during aggression, the lens would swing down giving the hen a red tinted perception of the environment.[16]
Rose-colored
History
A form of chicken eyeglasses was first patented in 1903 by Andrew Jackson Jr. of
Using chicken eyeglasses was still practiced in 1973, evident by a report in Illinois' The Hawk-Eye newspaper that a farmer had 8,000 chickens fitted with the rose-colored variety.[20] One inventor of a form of the glasses proposed legislation in Kansas to require all chickens in the state to be fitted with glasses, but his campaign was unsuccessful.[21]

- ^ The use of designs where the septum is pierced is illegal in some jurisdictions on welfare grounds. For example, in the UK's Defra Codes of Recommendations for the Welfare of Livestock: Laying Hens, provides: "The Welfare of Livestock (Prohibited Operations) Regulations 1982 (S.I. 1982 No.1884) prohibits ... the fitting of any appliance which has the object or effect of limiting vision to a bird by a method involving the penetration or other mutilation of the nasal septum."[26]
