Semiautomatic multiple apparatus designed to perform several vaccination interventions at the same time on birds of different ages. The device consists of a structure on which the animal is placed in a special housing that ensures correct positioning with respect to the actuators which, once activated by the operator, can perform up to four injections simultaneously in the animal's chest. At the same time, vaccination through perforation of the wing membrane for chickenpox is possible. The equipment is compact and easy to manage, adjustable in all parameters so as to be adapted to each animal size. It can be used in all combinations, even individually separated. It is supplied with supports able to adapt it to the different types of conditions in which it is used. It does not require any electrical supply. Just the connection to an air compressor.
