Modern Chaccu is a recreation of an ancestral technique, used since the pre-Inca times. People surround the vicunas to take them to stockyards in order to shear them.
The night before the Chaccu peasants do an offering to the Pachamama (Mother Earth), asking for the vicunas’ health and a sucessfull Chaccu. Once the animals are surrounded, peasants separe the youngest ones to avoid accidents, and also to evaluate them and register their data. Pregnant females are freed and so are the animals which fiber is shorter than 2.5 cms.

The shear is done with electromechanical scissors, doing it faster and reducing the animal´s stress. Plus a larger fiber is obtained.
