Did People Ever Put Glasses On Chickens?

There was a government research done done back in the 60s or 70s
That my Grandmother was involved in putting eye glasses on chickens
they were colored to see if this would reduce loss due to that chickens pick at each other creating sickness and death

No.it's a farmer's eye glass keeping a eye on his stock

Some people still do!Chicken glasses, or spectacles, date back over 80 years. The red-tinted glasses were placed on a chicken's beak to make the bird colorblind to the color red, thusly preventing chickens, who will peck at blood on another chicken, from pecking each other to death. Some versions were hinged and swung forward allowing for normal vision when leaning down to eat or drink.Who would have ever thought a chicken would be stylin' in rose-colored glasses?

What are you talking about? Why in the world would anyone put glasses on a chicken or any other animal for that matter? What purpose would they serve? This either has to be a joke or the most ridiculous question I've ever seen. Please explain yourself.
