Hello,

I have been a "lurker" for awhile now and I respect the views and opinions of most everyone on this forum. I will be making an incubator to hold twenty clutches. It will be 30" wide, 85" tall and 20" deep. I am making it out of 5/8" melamine with a 24x48 plexiglass view window in the front. I plan on really insulating this well using 1/2" styrofoam sheets all around and spray foam in the corners and in any gaps. It will also have a fan. My question is: Shouldn't some fresh air be allowed to enter? Should it be so air tight? I was thinking about putting a small vent in the back to allow for some air exchange. I live in Phoenix so there wouldn't be any chilly air entering. I want to do this right and appreciate any and all input. Thanks, Dan
