ADJUSTABLE FEEDING DEVICE FOR POULTRY. Abstract of the disclosure A feeding device, in particular for poultry, comprising an essentially dish-shaped pan with a bottom and an upright peripheral wall in which feed can be presented to the birds, and the bottom of which is provided with a central upright part, a drop tube for the supply of feed to the pan, the lower free end of which is situated centrally above the bottom of the pan, which drop tube can be moved over a limited, variable distance relative to the bottom of the pan in order to form a first feed supply opening of variable size between the bottom free end of the drop tube and the bottom of the pan, as a result of which feed can pass from the drop tube into the pan, and which drop tube at a distance from the free end is provided with one or more second feed supply openings, in the bottom position of the drop tube the first feed supply opening being closed and the second feed supply opening(s) being opened, and in the top position of the drop tube the first feed supply opening being open and the second feed supply opening(s) being closed, wherein the central upright part of the bottom of the pan extends in the bottom part of the drop tube and is formed in such a way that in the bottom position of the drop tube the top side of the central upright part reaches to the bottom edge of the second feed supply opening(s) and at that point shuts off the drop tube to the bottom thereof. The top side of the central upright part of the bottom of the pan preferably has a conical shape. The top side of the central upright part of the bottom of the pan, on the one hand, and the top edge of the second feed supply opening(s), on the other hand, preferably bound a passage which prevents a one- day-old chick from passing. In the bottom position of the drop tube the bottom edge of the second feed supply opening(s) advantageously lies lower and the top edge thereof lies higher than the top edge of the upright peripheral wall of the pan. Preferably, the bottom part of the drop tube which is below the second feed supply opening(s) is essentially conical-shaped.
