| 108376 | 2016.0166.001 | Eyeglasses | Aluminum (possible) frame with synthetic lenses | Anti-Pix | National Band & Tag Co. | United States of America | 1940 | circa | 1 | Dull silver coloured metal frame with two translucent red synthetic lenses attached on either side. | One of the frequent challenges faced by domestic chicken farming operation is the behavioral issue called feather pecking. Under normal conditions the feather pecking is light investigatory behavior where chickens probe each other. The behavior becomes problematic when the chicken being probed has feathers grasped or removed. When feathers are removed it can cause bleeding which in turn leads to cannibalism in the flock. A number of methods have been employed to combat the problems associated with feather pecking including beak-trimming flock size regulation selective breeding and eyewear. (From Artifact Worksheet see Ref. 1) | Eye-glasses developed for use in chicken farming to prevent feather pecking and cannibalism. (From Artifact Worksheet see Ref. 1) | The rose tinted glasses are designed to alter the colour of the image of the world around the chicken by filtering it through rose coloured glasses. The theory is that the chicken will not see the red colour of blood then the feather pecking behavior leads to bleeding thereby diminishing the cannibalistic behavior.
