Building a slatted rack

Hi @ABB the way @busso has made the rack is the original inventors design, the new cool way is to allow mites and beetles to be chased/drop through with out landing on the slats. I also made mine the traditional way.

The large entrance board is designed to reduce cool air/turbulance and promote the queen laying more eggs lower down and closer to the entrance.

See lnk below for more detailed explanation from Rusty.
