A poultry broth or chicken goggles is a plate mounted on poultry beak. The spectacle is not intended to improve visibility, it impedes this. Previously, the tool of metal, often aluminum, the modern version was made of plastic.
Birds can be the victim of poaching, something that can even lead to cannibalism. It is a recovery of the instinctive need in a group to determine a ranking. This is referred to as the example of the chicken behavior called the pitch order.
By limiting the bird's eye to the bird's eye it makes it almost impossible to damage other birds. For this purpose, the picture is mounted with a pen through the beak in front of the bird's eye. Serious forms of feathers are often caused by the manner in which the animals are kept. To avoid loss of animals, the glasses were previously widely used in poultry farming. Since the sixties of the last century, in the large-scale chicken and pheasant farms, the beaks are partly amputated, the so-called beacon fires.
The chicken goblet is in some areas a frequent 'encounter' of hobbyists who are looking for coins and other metal objects with a metal detector.
