A poultry feeder having an adjustment mechanism which adjusts the relative positions between the feeder tower and the feeder bowl to control the amount of feed entering the bowl that is readily adjustable, and, at the same time, enables the feeder bowl, the grill and the adjustment collar to freely rotate relative to the feeder tower to prevent damage to the adjustment mechanism when the grill and/or the bowl is contacted by the feeding birds. A lower edge of an adjusting collar rests on a shoulder portion of the feeder tower when the poultry feeder is suspended above floor level. The relative positions between a bottom of the feeder tower and the feeder bowl is adjustable in a plurality of discreet positions. Each of the plurality of discreet positions provides a different clearance between the bottom of the feeder tower and the bowl, thus controlling the amount of feed which may enter the bowl from the feeder tower.

1. A poultry feeder comprising: a) a feeder bowl having a peripheral portion and a central portion extending upwardly from a bottom of the bowl; b) a feeder tower including an upper feed inlet, an open bottom and at least one feed opening between the upper feed inlet and the open bottom; c) at least one feeder tower protrusion extending outwardly from the feeder tower, the at least one feeder tower protrusion having a shoulder; d) a collar mounted around the feeder tower, the collar having an outer surface with a plurality of upwardly open, axial notches, bottoms of adjacent notches being at different distances between uppermost and lowermost edges of the collar, at least one collar protrusion extending from the collar toward the feeder tower, the collar being axially movable relative to the tower between a first position, wherein the at least one collar protrusion is axially displaced from the at least one feeder tower protrusion permitting free rotation of the collar relative to the feeder tower, and a second position wherein the at least one collar protrusion contacts the at least one feeder tower protrusion to prevent relative rotation between the collar and the feeder tower; and, e) a grill having a hub through which the collar passes, a rim releasably attached to the peripheral portion of the feeder bowl and a plurality of spaced apart arms extending between the hub and the rim, the hub including at least one hub protrusion releasably engaging one of the plurality of axial notches in the collar, the grill being axially movable relative to the collar between a first position wherein engagement of the at least one hub protrusion with the axial notch of the collar prevents relative rotation between the grill and the collar, and a second position wherein the at least one hub protrusion is disengaged from the axial notches of the collar, thereby permitting relative rotation of the grill relative to the collar, whereby when the collar and grill are in the first positions, the collar, the grill and the bowl may rotate as a unit relative to the feeder tower. 2. The poultry feeder of claim 1 wherein the at least one hub protrusion comprises a plurality of adjacent hub protrusions, each having a different axial length. 3. The poultry feeder of claim 2 wherein the plurality of adjacent hub protrusions are parallel to each other and extend in an axial direction on the hub. 4. The poultry feeder of claim 1 further comprising first visual indicia on the grill adjacent to the collar and second visual indicia on the collar, the first and second visual indicia indicating relative positions of the grill and collar. 5. The poultry feeder of claim 1 further comprising a plurality of first tabs extending from the peripheral portion of the bowl and a plurality of second tabs extending from the rim of the grill, the first and second tabs releasably engaging each other to releasably attach the grill and the bowl together. 6. The poultry feeder of claim 1 wherein each of the plurality of spaced apart arms comprises a first portion extending downwardly from the hub adjacent to the feeder tower, and a second portion extending outwardly from the first portion to the rim. 7. The poultry feeder of claim 6 wherein the second portions of the arms are located below a plane of an uppermost surface of the rim. 8. The poultry feeder of claim 6 wherein the second portions of the arms are located within the bowl. 9. The poultry feeder of claim 1 wherein each of the plurality of spaced apart arms comprises a first portion extending outwardly from the hub and a second portion extending downwardly from the first portion to the rim.
