Some nest boxes on the market have nest pad material that covers both the laying and collection areas.  The Best Nest Box uses nest pad material in the laying area, but transitions to galvanized wire mesh in the collection area.    There are benefits to both approaches.  But here at Best Nest Box, we find that having wire mesh in the collection area offers the best overall experience.Benefits of wire mesh in collection area,Allows debris (manure, hay, straw, dirt, feathers, etc) a way to make it out of the box by falling through the 1-inch square holes in the wire mesh.Provides a more hygienic collection area since nest pads have lots of crevices for debris to get trapped.Wire mesh is quicker and easier to clean than a nest pad.  Nest pad material has a lot of hard-to-reach surface area that is more difficult to clean.Wire mesh is more durable than nest pad material.  Frequent shaking and cleaning of nest pads may result in tears and the need for replacement sooner.Here's a video of a farmer using another manufacturer's nest box which uses pad material in the collection area. The farmer mentions "collecting the poop".Benefits of nest pad material in collection area,In dusty environments (like stationary coops), dust on the wire mesh can leave dust lines on your eggs when they roll on to the mesh with their "bloom" (a moist protective layer that eggs have when they are laid).  However, this problem can be alleviated by quickly wiping your collection area with a moist towel daily after egg collection or less frequently as-needed.
