In a breeder house for chickens, nests are aligned on both sides of a center aisle with their entrance openings facing slatted platforms on the sides of the house. The nests are supported by brackets on roof-support stanchions and are positioned so that chickens can move underneath the nests from the platforms to the floor of the aisle. A hoist system is provided for simultaneously raising the nests to facilitate cleaning. Each of the brackets has a first part secured to a nest and a second part removably secured to a stanchion. The first and second parts can be readily separated by the removal of two bolts on each bracket to permit the nests to be raised with one bracket part remaining attached to the nest and the other part remaining attached to the stanchion. The part attached to the stanchion is held by the engagement of L-shaped slots with projections on the stanchion and can be removed readily.
