The feeding apparatus has a pecking block which is moveably mounted and mechanically coupled to the feed valve mechanism in such a way that the feed valve mechanism is closed when the pecking block is in a neutral position and the feed valve mechanism is open when the pecking block is in a deflected position due to pecking at the pecking block. ## Claims ### Claim 1 A feeding apparatus for poultry comprising: a feed source; a feed line connected to the feed source; a feed valve mechanism arranged in the feed line and which in a closed valve position blocks feed from passing through the feed line and in an open valve position allows feed to pass through the feed line; a pendulum rod swingingly mounted in the feeding apparatus and mechanically coupled to the feed valve mechanism; wherein the feed source is disposed above the feed valve mechanism, and feed drops out of the feed source under the influence of gravity when the feed valve mechanism is in the open position, and a pecking block moveably mounted and mechanically coupled to the pendulum rod, wherein the feed valve mechanism is closed when the pecking block is in a neutral position and the feed valve mechanism is open when the pecking block is in a deflected position due to pecking at the pecking block, wherein the pendulum rod is swingingly mounted in a pendulum bearing arranged above the pecking block and below the feed valve mechanism. ### Claim 2 (depends on 1) The feeding apparatus according to claim 1, further comprising an annular disc having a central through bore that is larger than a cross-sectional dimension of the pendulum rod and through which the pendulum rod extends; a pendulum bearing ring fixed to the pendulum rod and defining a pivot fulcrum disposed below the feed valve mechanism and about which the pendulum rod may swing, the pendulum bearing ring having an outer diameter larger than the central through bore in the annular disc, whereby the pendulum rod is prevented from slipping downwards out of the central through bore in the annular disc. ### Claim 3 (depends on 1) The feeding apparatus according to claim 1, wherein the annular disc comprises a plurality of lateral discharge holes distributed around its circumference to allow feed to pass through the feed line. ### Claim 4 (depends on 1) The feeding apparatus according to claim 1, wherein the pendulum rod projects upwards a predetermined distance above the feed valve mechanism within the feed line to causes a loosening movement within the feed line when the pendulum rod is deflected, thus counteracting jamming and resultant clogging of the feed within the feed line. ### Claim 5 (depends on 1) The feeding apparatus according to claim 1, wherein the feed valve mechanism comprises a through hole and a valve member mechanically coupled to the pecking block, wherein the through hole is closed when in the neutral position and the through hole is open at least partially when the pecking block is in the deflected position. ### Claim 6 (depends on 5) The feeding apparatus according to claim 5, wherein the valve member is fixed to the pendulum rod above a pendulum bearing and the pecking block is fixed to the bottom end of the pendulum rod. ### Claim 7 (depends on 1) The feeding apparatus according to claim 1, wherein the pecking block includes an abrasive material. ### Claim 8 (depends on 1) The feeding apparatus according to claim 1, wherein the pecking block includes a mineral material. ### Claim 9 (depends on 1) The feeding apparatus according to claim 1, wherein the pecking block has an upper end face onto which the feed falls when in the deflected position and on which at least parts of the feed remains lying. ### Claim 10 (depends on 1) The feeding apparatus according to claim 1, wherein the feed source comprises a valve opening at a bottom end which opens into the feed line and a valve member operably coupled with the valve opening, and the pecking block is fixed to a bottom end of the pendulum rod which carries in an upper end portion thereof the valve member which closes the valve opening when in the neutral position and opens the valve opening at least partially when in the deflected position, the pecking block further being swingingly mounted in the feed line at a position between the upper end portion and the bottom end of the pendulum rod. ### Claim 11 A feeding apparatus for poultry, comprising: a feed source; a feed line in communication with the feed source and having an outlet opening; a feed valve mechanism disposed within the feed line and between the feed source and the outlet opening; a pendulum rod swingingly mounted in the feeding apparatus and mechanically coupled to the feed valve mechanism; an annular disc having a central through bore that is larger than a cross-sectional dimension of the pendulum rod and through which the pendulum rod extends; a pendulum bearing ring fixed to the pendulum rod and defining a pivot fulcrum disposed below the feed valve mechanism and about which the pendulum rod may swing; and a pecking block movably suspended from and operably coupled with the pendulum rod, wherein the feed valve mechanism is closed when the pecking block is in a neutral position and the feed valve mechanism is open when the pecking block is in a deflected position. ### Claim 12 (depends on 11) The feeding apparatus of claim 11, wherein the annular disc comprises a plurality of lateral discharge holes distributed around its circumference to allow feed to pass through the feed line. ### Claim 13 (depends on 12) The feeding apparatus of claim 12, wherein the outer diameter of the pendulum bearing ring and the diameter of the through bore of the annular disc cooperate to prevent the pendulum from slipping downwards out of the central through bore of the annular disc. ### Claim 14 (depends on 13) The feeding apparatus of claim 13, wherein lateral deflection of the pecking block opens the feed valve mechanism. ### Claim 15 (depends on 11) The feeding apparatus of claim 11, further comprising a distribution cone suspended beneath the outlet opening. ### Claim 16 (depends on 11) The feeding apparatus of claim 11, wherein the pecking block is a flat, rotationally symmetrical disk of circular cross section. ### Claim 17 (depends on 11) The feeding apparatus of claim 11, wherein the pecking block is an elongated cylindrical body. ### Claim 18 A method of dispensing feed, the method comprising the steps of: placing feed into a feed source; connecting a feed line to the feed source, the feed line having an outlet opening; placing a feed valve mechanism within the feed line and between the feed source and the outlet opening; fixedly mounting an annular disc having a central through bore within the feed line; fixing a pendulum bearing ring about a pendulum rod to define a pivot fulcrum about which the pendulum rod may swing; placing the pendulum rod within the feed line and through the central through bore of the annular disc, wherein the central through bore is larger than a cross-sectional dimension of the pendulum rod, whereby the pendulum rod extends through the central through bore of the annular disc and is swingingly supported by the annular disc below the feed valve mechanism; mechanically coupling the pendulum rod to the feed valve mechanism; and suspending a pecking block from the pendulum rod, wherein the valve mechanism is closed when the top pecking block is in a neutral position and the feed valve mechanism is open when the pecking block is in a deflected position. ### Claim 19 (depends on 18) The method of claim 18, further comprising the step of providing a plurality of lateral discharge holes distributed around a circumference of the annular disc to allow feed to pass through the feed line. ### Claim 20 (depends on 19) The method of claim 19, further comprising the step of suspending the pendulum rod via a pendulum bearing ring disposed about the pendulum rod and supported by the annular disc.
