Abstract: The feeding device especially for chicken farming substantially comprises a cylindrical upright distributor (4) located above a containing plate (1) and connected at the upper part thereof to a feed-carrying horizontal tubular duct (5) supported by ropes (6). The distributor (4) is moved close to the plate (1) causing a reduction of the feed (7) level in the plate (1) by lowering the tubular duct (5). In addition, the distributor (4) has a pair of vertical recesses (8) and within each of them a C-shaped flat spring (9) is accommodated thereby forming a detent (10) into which a tooth (11) present on an annulus (3) integral to the plate (1) and disposed about the distributor (4) can be snap-fitted. In this way the feed level can be simultaneously reduced in all plates (1) of the distribution line by merely lowering the horizontal duct (5).
