ABSTRACT:
A hay enclosure includes two end sections and two sections along each side. Diagonally opposite side sections are equal in length, although the two sections on each side have different lengths. The enclosure is pivotally movable to a second position wherein two triangular-in-shape enclosures are formed having an area smaller than the rectangular enclosure area. A circular enclosure includes four arcuate sections which may be collapsed about a bale of hay into two pillow-shaped enclosures. Adjacent sections are pivotally interconnected by vertically spaced apart hinges, with the upper hinge including a downwardly extending pin received in a sleeve, and the lower hinge including a pair of abutting vertically aligned sleeves in which a movable pin is received.
A horse hay feeder section includes inverted spaced apart U-shaped spacers providing horse head feeding stations therebetween and being open at the top whereby a horse may raise its head and turn it away over one of the adjacent spacers.
