MADE IN THE USA: Created from Great Lakes Aspen Excelsior Fibers - 10 pack of premium quality 13" x 13" poultry box liners | HEALTHY CHICKS: Excelsior box pads help to provide secure footing for newly hatched chicks and poults. This creates a winning environment for the flock or brood. | COST EFFECTIVE WITH MORE HATCHABLE EGGS: Aspen nest pads help to provide cleaner, fresher and more hatchable eggs. They can be used with any size nesting box and are easy to place in the nesting box. | EASE OF GATHERING: The eggs are on top, clean and fresh rather than having to hunt and dig through bedding. This allows for faster egg gathering. | MOISTURE CONTROL: The nesting material absorbs moisture while keeping eggs clean. These work great in a large or small coop environment saving on the use of other chicken supplies.
