This invention relates to laying nest having a rack drive expulsion system. As disclosed herein, the invention preferably comprises a laying nest for hens comprising a box and a rack drive floor expulsion system. The floor pivotably moves between first and second positions by virtue of a gear rack that is fixedly connected to and disposed within the box, and a gear wheel that is rotatably connected to the floor. Accordingly, the expulsion system provides for the selected removal of hens from the laying nests as desired.

A nesting cavity for birds having a false floor of a screen or perforated material above a sloped floor that terminates at its lowest elevation with exposure to the exterior of the nest cavity. This exposure allows debris, water and nest parasites that fall through the false floor to exit the cavity when natural forces such as gravity act on the materials that reach the sloped floor. Increased ventilation as a result of this exposure aids in lowering moisture inside a nesting cavity and moderates a cavity temperature.

A mounting bracket having more desirable utility as compared to known embodiments includes a first flat surface for mounting to a box, shelf, or structure, and a second curved surface for mounting to the header of a railing or fence. The bracket can mount to multiple boxes, shelves, and structures, and does not require tools for installation to the railing or fence.

A swift let breeding facility, for use in creating and harvesting edible bird's nests. The facility includes sub-systems for injecting live insect and worm prey, and water, into an aerial enclosure to provide a feeding system imitative of a natural swift let feeding environment.

A biodegradable duck nesting system includes a first member having a hollow interior, and a second member disposed in the first member. The system includes a biodegradable hollow enclosure having an opening sized to allow a duck to enter and/or exit the enclosure. The system also includes a predator prevention member located below the enclosure for preventing predators from contacting the enclosure.
